It supports LED, HMI, fluorescent, tungsten, natural light, and flash, covering most common sources encountered in image-making and controlled environments. A 270-degree swivel head allows the meter to be oriented while remaining connected to a fixture, and dark calibration without a cap helps simplify setup. Customization functions and storage for as many as 99 measurements are valuable for repeat checks and established reference conditions.
The main limitation is its focus. The C-800 evaluates light and its rendered color rather than measuring reflected color from paint, print, or physical samples. Users who need solid-material spectrophotometry should favor the Nix or other reflectance instruments. Even for lighting work, the large display is an advantage, but it does not make this model interchangeable with a full laboratory spectral analysis system.
The C-800 is a compelling pick for photographers and filmmakers who want a screen-rich, portable light meter with broad source compatibility.

We may earn a commission when you buy through this link, at no additional cost to you.
The targeting jig is not merely an accessory; the product information states that the device will not function without it. That requirement creates a clear trade-off. Buyers gain a controlled way to place the small measurement aperture over precise print targets, but they must accept a workflow designed specifically for print rather than a general-purpose instrument for paint, plastics, or lighting.
The device is suggested for use with Nix Print Pro software, which is sold separately. That software can uncover actionable insights intended to help print operations reduce waste and minimize downtime. The free Nix Toolkit app remains available for Android and iOS, and enhanced compatibility with Pantone, RAL, and NCS libraries is offered through a subscription. These options make the device relevant to studios working within structured color-management systems.
The 2mm model is best for print and packaging professionals who routinely work with control strips and require repeatable target positioning. It is less attractive to general buyers because of the mandatory jig and narrower application focus. If the task is evaluating lights, identifying an arbitrary paint color, or measuring a large physical sample, the standard Nix Spectro 2 or another instrument in this roundup is a better fit.
Consistent Placement Matters
The 2mm targeting jig helps operators position the instrument over small print targets on a control strip. Consistent placement is especially important when data will be used to identify deviations and guide press adjustments.
A Deliberately Narrow Workflow
The mandatory jig and recommended use with Nix Print Pro make this a specialized production tool. Its strengths become apparent when print-control consistency matters more than general-purpose flexibility.

A physical observation window helps operators monitor measurement placement and reduce errors. The instrument provides color density, dot area, overprint rate, print contrast, hue error, and grayscale measurements, taking it beyond a basic reflectance reading.
The stated repeatability of dE*ab at or below 0.02 is a notable precision claim for repeat checks. Output includes spectral reflectance, CIE-Lab, CIE-LCh, Delta-E, covering power, whiteness, yellowness, and more than 30 other indicators, with nearly 40 evaluation illuminants including D50, D55, and D65. Connectivity to Android, Apple, and Hongmeng devices adds workflow flexibility, though buyers should verify app and cable support for their own platform.
This densitometer is best for print and packaging users who want detailed solid-color analysis without selecting a general lighting meter. It is particularly useful for comparing control patches, checking overprint behavior, and monitoring production consistency. Those seeking broad paint libraries, spectral charts, or light-source evaluation will find other options more aligned with their needs.
Measurement Built for Print
Density, dot area, overprint rate, print contrast, hue error, and grayscale outputs address practical press and packaging concerns. These functions make the instrument more specialized than a generic color meter.
Placement and Sample Flexibility
The observation window helps users keep the sensor correctly positioned, while three aperture sizes accommodate different sample sizes. Together, they support more consistent measurements across varied print conditions.

Pros
- Simple sample-based transmission workflow
- Displays three results simultaneously
- Supports eyewear and lens testing
- Automatic calibration reduces setup
- Compact and task-focused
Cons
- No available customer rating
- Accuracy applies to clear materials
We may earn a commission when you buy through this link, at no additional cost to you.
Its listed resolution is 0.1%, while the stated plus or minus 2% accuracy applies to colorless and transparent material. Purple-light peak wavelength is 395nm, blue-light peak wavelength is 430nm, and the visible-light range spans 380–760nm. These parameters make the readings directly relevant to businesses evaluating protective lenses, optical coatings, and computer accessories.
Self-calibration and auto-calibration are useful for a repetitive inspection workflow because the operator can place a sample and obtain results without manual adjustment. The trade-off is specialization. It does not offer the color-temperature, illuminance, CRI, spectral graph, or reflectance functions found elsewhere in the roundup, and the stated accuracy should not be assumed to apply equally to tinted or otherwise complex materials.
This transmission meter is best for optical shops, eyewear sellers, lens-accessory businesses, and product testers who need a simple answer about visible, blue, and purple-light transmission. It is a better fit than a full spectrophotometer when the operational question is simple: how much light passes through this sample?
Focused Optical Questions
The instrument concentrates on transmission percentages for visible, blue, and purple light. That focus makes it easier to use for lens and anti-blue-light material evaluation than a general spectral analyzer.
Minimal Calibration Routine
Self-calibration and automatic calibration support fast, repeatable checks. Operators can place a sample in the testing position and read the three transmission values simultaneously.

- ColorExpert workflow needs PC software
We may earn a commission when you buy through this link, at no additional cost to you.
A dual optical path is credited with improving repeatability, while more than 30 measurement parameters and nearly 40 evaluation illuminants support a broad range of color decisions. A visual feature allows the operator to observe the measured area, which helps avoid sampling the wrong part of a material. The instrument also supports the PC-based ColorExpert color-management system.
Long-term stability is another strength. The product includes a calibration base and a zirconium reference with a stated Mohs hardness of 9 for calibrating the instrument. This matters because handheld color measurements depend on clean optics and consistent reference conditions, especially when users compare samples over time or across a production run.
This model is a strong recommendation for paint, printing, coatings, and quality-control users who need detailed color-difference data and a large local record capacity. It is less directly aligned with lighting evaluation, spectral waveform inspection, or transparent-material transmission testing. Buyers should review the ColorExpert interface and confirm their required measurement outputs before ordering.
Repeatability for Quality Control
The dual optical path and stated dE*ab repeatability of 0.04 or better address a central concern in color QC: whether repeated readings remain consistent. That makes the instrument relevant to pass/fail comparisons and production documentation.
Large Local Data Capacity
Storage for 10,000 measurements reduces the need to transfer every result immediately. The color-management software and reference-calibration accessories support a more structured laboratory or production workflow.

We may earn a commission when you buy through this link, at no additional cost to you.
The three-and-a-half-inch IPS touchscreen simplifies field operation, and PC software control supports more detailed review and data analysis. The device also provides comparative testing, transmittance analysis, and real-time monitoring. These functions allow users to compare sources, examine selected optical behavior, and retain test data for later evaluation.
Durability is the major differentiator. The housing is described as waterproof, oil-proof, and resistant to extreme temperatures, while enhanced optical components are intended to minimize stray light. Those qualities are especially appealing for commercial, architectural, healthy-lighting, and industrial checks performed in changing environments rather than controlled laboratory benches.
The HP320 is best for lighting evaluators, photographers, facility teams, and field researchers who need CCT, CRI, illuminance, and spectral results in a tough enclosure. It is less suitable for print solids, paint matching, and near-infrared work. Buyers should confirm the full parameter list, calibration process, and included accessories because the supplied information focuses more on construction and core readings than workflow-specific details.
Built for Changing Work Environments
Waterproof, oil-proof, and temperature-resistant construction gives the HP330-style field approach a practical foundation. Rugged protection is valuable for commercial buildings, factories, outdoor installations, and other demanding locations.
Core Lighting Metrics Together
Color temperature, CRI, SDCM, and lux measurements cover several common lighting questions in one device. Real-time monitoring and stored data add value for repeat checks and comparative source testing.

Buying Guide – How to Choose the Best Spectrometer 2
The right Spectrometer 2 depends on whether you are measuring emitted light, reflected solid color, spectral output, or transmission through a material. Consider the application, wavelength range, accuracy, interface, software, calibration system, portability, and workflow restrictions before choosing.
Define the Measurement Target
Start by identifying what you need to measure. Photographers, filmmakers, and lighting designers usually need color temperature, illuminance, CRI, and other source metrics, making the Sekonic C-7000 or C-800 more relevant. Print operators may need density, dot area, overprint rate, and control-strip readings, while paint and coating users need reflectance and Delta-E measurements. Eyewear and lens testers need visible, blue-light, and purple-light transmission rather than general spectral analysis.
Choose the category that directly matches the sample and the decision you need to make. A light-source meter cannot substitute for a solid-material spectrophotometer, and a transmission tester is not a general lighting analyzer.
Check Wavelength Coverage
Visible-light instruments commonly cover approximately 380–780nm, while extended-range tools may reach 1050nm and include near-infrared output. A broader range is useful for LED engineering, environmental analysis, and specialized laboratory work, but it does not automatically make an instrument better for ordinary photography or print control. Match the coverage to the light sources and phenomena you actually need to evaluate.
For most visible-color and lighting tasks, a stated visible range is sufficient. Choose extended coverage when near-infrared performance is central to your testing.
Prioritize Relevant Accuracy
Accuracy specifications matter most when measurements will be compared, documented, or used to make production adjustments. The CMYK 2 claims dE*ab repeatability of 0.02 or better, the D/8 model states repeatability of 0.04 or better, and the transmission meter lists plus or minus 2% accuracy for clear and transparent material. These figures apply to different measurements and should not be compared as if they represent the same metric.
Check whether the manufacturer states wavelength accuracy, color repeatability, or transmission accuracy, then compare figures of the same type. Also review the conditions and materials to which each claim applies.
Consider Workflow Software
Software can determine whether an instrument is convenient for daily use. Nix products use the free Toolkit app, with Nix Print Pro offering enhanced print quality-assurance features and premium Pantone, RAL, and NCS access requiring a subscription. The D/8 model works with ColorExpert, the 380–1050nm analyzer includes PC software for spectral graphs, and the HP320 supports PC control. Confirm which platform you use and whether advanced features are optional.
Free core software is attractive for occasional users, while subscribed libraries and production modules can be worthwhile for high-volume color workflows.
Evaluate Portability and Controls
Portability means more than low weight. A compact device with a touchscreen can be faster in the field, while a swiveling sensor head may improve positioning under a fixture. Some print devices require a targeting jig and have a deliberately restricted workflow. Check the required accessories, setup procedure, sensor positioning, and whether one-handed operation is necessary for your work environment.
The best portable instrument is the one you can position accurately and operate consistently in the locations where measurements are required.
Choose the Right Aperture
Aperture determines the area being measured and can be critical for small targets, detailed print patches, or large uniform samples. The CMYK 2 supports 11mm, 5mm, and 3mm openings, while the D/8 model offers 8mm and 11mm options. The Nix 2mm version is even more specialized and requires its targeting jig. Match the aperture to the physical scale of the sample rather than choosing the smallest available opening by default.
Smaller apertures improve spatial selectivity, while larger apertures can be easier to align on broad or uneven surfaces. Confirm that the target fits within the measurement area.
Review Calibration and Storage
A reliable instrument needs a sound calibration routine. The D/8 model includes a calibration base and zirconium reference, the transmission meter supports self- and auto-calibration, and several lighting products provide built-in calibration processes. Storage is also important: the Sekonic C-800 stores 99 measurements, while the D/8 unit stores 10,000 records. Decide how much local history your workflow needs and whether PC transfer is acceptable.
Frequent users should make calibration accessories and dependable recordkeeping part of the purchase decision, not an afterthought.
Balance Features Against Specialization
A feature-rich instrument can still be wrong for a narrow job. The Nix 2mm requires a jig, the transmission tester focuses on transparent samples, and the CMYK 2 emphasizes printing indicators. General users may get better value from a versatile visible-light meter, while specialists often benefit from a dedicated workflow. Avoid paying for unrelated functions if they do not improve the measurements you will make.
Prioritize the smallest set of features that fully supports your use case, then consider expandability, storage, and future needs.
How to Use and Care for Your Spectrometer 2
Begin by reading the device-specific instructions, charging or replacing batteries as required, and checking the sensor window for dust, fingerprints, scratches, and residue. Perform the recommended zero or white calibration under suitable conditions before collecting data. Keep calibration surfaces clean, avoid touching optical components, and confirm that the stated warm-up or stabilization period has been completed.
For a representative reading, place the instrument in the same orientation and distance used during calibration. On a lighting meter, aim the sensor toward the source and avoid blocking the field of view. On a solid-color instrument, use the correct aperture and position the sample over a flat, representative area. A print targeting model must use its jig, and a transmission tester should receive the sample exactly as instructed.
Record the measurement, device settings, illumination, sample identity, and environmental conditions so that later readings remain meaningful. Compare results using metrics appropriate to the task, clean the sensor after use, and store the instrument in its protective case away from excessive heat, moisture, and direct sunlight. Recalibrate before important sessions and follow the manufacturer's guidance for software updates and reference materials.
Frequently Asked Questions
What is the difference between a spectrometer and a spectrophotometer?
A spectrometer records spectral information, often across wavelength bands, while a spectrophotometer typically evaluates spectral reflectance or transmission for color analysis. A color-and-illuminance meter may report selected spectral metrics without providing the same detailed reflectance data. The right choice depends on whether you are evaluating a light source, a solid material, or light passing through a sample.
Is the Sekonic C-7000 suitable for photography and video lighting?
Yes, its measurement modes cover LED, HMI, fluorescent, flash, and natural light, while illuminance readings add practical exposure context. Expanded metrics such as TM-30, TLCI/TLMF, SSI, and CRI comparison are especially relevant to image makers. It is most useful when choosing fixtures, comparing sources, or building repeatable lighting setups.
Which model is most appropriate for print and packaging quality control?
The Nix Spectro 2 2mm is specifically designed for positioning over print control strips, while the CMYK 2 provides density, dot area, overprint rate, contrast, and other printing indicators. The standard Nix Spectro 2 also supports print workflows and broader material analysis. Choose according to whether control-strip targeting, detailed press indicators, or cross-material flexibility matters most.
Can a Spectrometer 2 measure paint and coatings?
The standard Nix Spectro 2 and the D/8 handheld spectrophotometer are better matches for paint and coating work than lighting-focused meters. They are designed to report reflectance and color-difference information, while the Nix app provides access to a large library of named paint colors. Compatibility with a particular reference system may depend on the app or an optional subscription.
Do I need one of the products with near-infrared coverage?
Only if your application includes near-infrared output or a broad spectral range extending beyond visible light. The 380–1050nm handheld analyzer is designed for that type of work, while visible-only instruments cover common lighting, color, and print requirements. Wider range can be useful, but it should match a genuine need rather than simply add complexity.
How important is calibration for accurate color readings?
Calibration is essential because it establishes the instrument's reference response and helps maintain consistent results over time. Use the specified base, reference material, white standard, self-calibration process, or other method supplied with the specific model. Keep optical windows clean and recalibrate when results shift unexpectedly, after a change in conditions, or before an important production run.
Can these instruments test anti-blue-light glasses?
The dedicated Spectrum Transmission Meter is designed for glasses, anti-blue-light materials, glass, and mobile-phone lenses. It displays visible, blue-light, and purple-light transmission after the sample is placed in its testing position. General color meters may provide related spectral data, but they are not optimized for the same quick transmission workflow.
Should I consider products without published customer ratings?
Yes, but use additional care when evaluating them. Customer ratings can offer useful evidence about setup, reliability, software, and accuracy, yet a single rating or no rating does not prove performance either way. Compare the stated specifications, included accessories, application fit, warranty, calibration process, and return terms, and seek documentation for the measurements you need.
Final Thoughts on Choosing the Best Spectrometer 2
The Sekonic C-7000 is the strongest all-around pick for lighting evaluation because it combines portable spectral analysis, illuminance readings, and expanded color-interpretation metrics. The Nix Spectro 2 stands out for professional material color work across print, paint, packaging, and coatings, while the CMYK 2 Color Densitometer provides focused print-production functions and an established 5.0 customer rating.
Prioritize the measurement that directly affects your decision rather than the longest feature list. Lighting professionals should consider source types, spectral interpretation, and illuminance; print teams should examine apertures, density indicators, positioning, and workflow software; material specialists should focus on reflectance and Delta-E repeatability; and optical testers should prioritize transmission-specific results and calibration.
Before ordering, verify the current listing, wavelength range, software compatibility, required accessories, calibration supplies, warranty, and return terms. Product availability and pricing can change, so current information should be checked at the point of purchase to ensure the selected Spectrometer 2 matches both the application and the budget.
