The average fluctuation of △E is less than 0.07, actually more in 0.03~0.06.
Portable structure design which is more conductive to keeping the instrument stable when using.

Illumination locating is a fast, simple and convenient locating function which is the original function by 3nh.

3nh has the intellectual property of PC software. The corresponding software serial number and
password protection are configured in 3nh colorimeter.
Be able to perform color difference analysis, color difference cumulative analysis, chromaticity index, color sample database management, simulating object color, etc.

3nh is the first enterprise using high capacity Li-ion battery in colorimeter.
3nh Li-ion battery can be repeatedly charged which will save cost. Meanwhile, it can measure more than
3000 times on one charge to ensure the stability of long time measurement.

FAQs About NH300 Colorimeter
A spectrophotometer illuminates a sample with light or passes light through it and records the reflected or transmitted light over the wavelength range. It transforms this data into color coordinates (such as L*a*b*), allowing accurate color assessment as well as color comparison to standards.
Colorimeter,Gloss meter,Coating thickness meter,window tint meter,UV meter, Leeb hardness tester, Ultrasonic thickness gauge. Threenh Technology company adheres to independent design, research and development, production and sales of various measuring instruments.
The "accuracy" of a colorimeter refers to how closely its measurement results align with the true values, primarily influenced by systematic errors and random errors, how closely its measured color data (e.g., Lab values, density) aligns with the true color properties of a sample or certified standard. Specifically, it includes key indicators such as color coordinate accuracy, luminance accuracy, and data repeatability.
It reflects the instrument’s ability to minimize deviations caused by component variations, environmental factors, or calibration drift—ensuring results reliably represent the actual color, which is critical for quality control and brand consistency in industries like printing, food, textiles, paint and coatings.
Yes. We can supply OEM and make customized design for any specific application. Our MOQ for OEM and ODM service is 5 pcs for one model. We can not only offer standard machines, but also customized machines. Don’t hesitate to tell us your requirement, we will try our best to meet your needs.
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.
