Multi-angle Spectrophotometer Instruments

3nh Multi-angle spectrophotometer is used to measure the color difference for the surface paint which is affected by different viewing angles and viewing conditions.

Redefine Color Measurement for Complex Surfaces 

 The 3nh Multi-Angle Spectrophotometer features up to 12 measurement angles, with a maximum repeatability of ΔEab < 0.04 and color repeatability of ΔEab < 0.02. It is primarily designed for measuring the sparkle, flop, and granularity effects on object surfaces,It can provide accurate and consistent color measurement for metalllics, pearlescents and other complex special effect finished products. 

 It can not only measure multi-angle color difference, but also measure and characterize special finishes through multiple measuring angles. Even in the curved surface, it also has high measuring accuracy and stability.

FAQs About Multi-angle spectrophotometer

The repeatability is an important parameter for the accuracy of the colorimeter. Threenh Technology portable colorimeter for color measurements tandard deviation ΔE*ab is within 0.03 (Measurement condition: the average value of 30 measurements on the white board at an interval of 3s after calibration). Each colorimeter can pass the qualified inspection before leaving the factory to ensure it conforms to the standard of China Metrology Institute.

Gloss level is the extent of reflectance of light on a surface. It measures the shininess or dullness of a finish, from flat or matte to high gloss. It is important in aesthetic, functional, and quality control applications.


The most important equation is A = 2εcl, where A is the absorbance, 2 is a constant, ε is the molar absorptivity (L/mol cm), c is the concentration (molL-11), and l is the path length (cm). This can be used to relate the absorbance to the concentration, allowing quantification through colorimetric assays.


The principle of colorimetry is the law of Beer-Lambert, which says that the intensity of light absorbed by a colored solution is proportional to the concentration of the absorbing species and the path length. It measures the extent of light that is absorbed at certain wavelengths.


a. Users must specify Standard File Name, Sample File Name and Sample Database File Name when first use.

b.Standard File is use to store standard measurement data. Sample File is used to store sample measurement data. Sample Database File is used to store the measured data exported from sample records.
