3nh Spectrophotometers for Paint Formulation 

For paint formulation accuracy, the 3NH top spectrophotometers prioritize high spectral resolution, excellent repeatability, superior inter-instrument agreement (IIA), d/8° integrating sphere design, and compatibility with advanced formulation software. Below are the leading models

  1. 3nh TS8560 Premium Benchtop Spectrophotometer  (Lab & R&D – Highest Accuracy)

    High precision with d/8° integrating sphere, excellent repeatability and inter-instrument agreement. Ideal for laboratory color analysis, accurate paint formulation and strict quality control. Perfect for opaque and translucent paints. Pairs seamlessly with Pecolor software for precise recipe calculation.

  2. Best for: High-end industrial coatings, R&D, and demanding formulation labs, High-volume paint labs, global color standardization

  3. 3nh TS7700 Portable Spectrophotometer

    Compact and easy to operate, supports SCI/SCE measurement. Perfect for on-site color matching, production line inspection and daily paint tinting control. Seamlessly connects to PeColor for on-the-go formulation, rugged, easy-to-use, designed for high-throughput retail environments.

  4. Best for: Retail paint stores, fast, accurate counter matching, On-site tinting, production line checks

  5. 3nh MS3008 Multi-angle Spectrophotometer

    Professional for metallic, pearlescent and special-effect paints. Captures angular color variation to meet high-end automotive and coating formulation requirements. Captures complex light behavior for perfect effect-paint matches.

  6. Best for: Automotive, specialty coatings


All these instruments deliver superior performance by measuring precise spectral data, which is the foundation for accurate, repeatable, and cost-saving paint formulation.

Zero calibration of a hazemeter is a critical pre-measurement procedure to ensure the instrument’s accuracy by resetting its baseline to "zero" when no haze or light attenuation is present.

  1. Align the hazemeter’s measurement window with air or a black background, ensuring no objects block the window.

  2. Press the hazemeter’s zero calibration button and wait for the instrument to complete automatic calibration. At this point, the instrument should display a zero haze value and a zero light transmittance value.

  3. Observe the instrument’s display to confirm the zero calibration result stabilizes near zero. If the zero calibration is inaccurate, repeat the above steps multiple times until the displayed haze and light transmittance values stabilize near zero.

Perform 0-degree calibration before testing, this eliminates inherent instrument drift, environmental interference, or residual signal errors, ensuring subsequent measurements of transparent/translucent samples (e.g., plastic films,pvc, glass, coating, displays and cosmetic packaging) are reliable. Correct for minor instrument deviations caused by long-term use, temperature changes, or power fluctuations.

A colorimeter is a quick and inexpensive method to measure color and to control color in a material or solution. It is used to maintain color consistency during production and to check the chemical concentration. It also assists with the quality control of labs, food, textiles, and pharmaceuticals.


Testing metamerism helps to identify color matches that look the same but are different in different lighting. This helps in ensuring that materials are of the same quality in all light settings.


The automotive, aerospace, metal finishing, marine, construction, and manufacturing industries utilize and rely on coating thickness gauges the most. They ensure that coatings are within the expected criteria for functionality, safety, and durability.
