FAQs About  Geometric Test Charts

Ensure the source, viewing angle, and background are all neutral and standardized, and the samples are clean, and positioned for a side-by-side comparison under each light condition.


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.

A spectrophotometer measures the full visible color spectrum (typically 400–700 nm). It offers significantly higher precision and enables detailed evaluations – including spectral curves, ΔE values, and color distance measurements. It is the preferred choice for demanding applications in labs or color development environments. learn more..

The core difference between a colorimeter and a spectrophotometer lies in their light measurement methods. A colorimeter measures color values based on the tristimulus method (e.g. LAB or RGB) and compares the sample to a reference. It's ideal for quick, repeatable measurements under consistent conditions – such as in production or incoming goods control.

Make sure the light sources are calibrated, keep extraneous light sources away, have the correct viewing angles, and handle the samples in a clean and uniform manner.


High Measurement Accuracy and Stability: Low ΔE fluctuation (e.g., NH300: ΔE < 0.07; NR10QC: ΔE ≤ 0.03 short-term repeatability); Reliable sensors (CMOS dual-beam/silicon photodiode) and long-lasting light sources (1.6M–3M measurements over 5 years).

User-friendly Design and Convenient Operation: Intuitive interfaces (e.g., NH300’s “fool-proof” operation), auto-calibration, and ergonomic grips for extended use; Versatile positioning (light/cross alignment) for precise measurements.

Robust Design: Our colorimter instruments are designed to withstand rigorous use, providing long-term reliability. Rechargeable lithium batteries enable 5,000–6,000 measurements per charge (e.g., NH300/TS7030), ensuring cost-effective durability.

PC Software Support for Functionality Expansion: PC software (e.g., CQCS3) supports color difference analysis, chromaticity indexing, and sample library management.

Global customer support: Our global presence across regions ensures you get the service and maintenance support you need to keep your instrument at peak performance. 

Multiple Measurement Apertures and Application Scenarios: Multiple measurement apertures, different models have different measurement apertures and some models offer multiple optional apertures. Applicable to plastic electronics, paint and ink, textile and garment printing and dyeing, printing, ceramics, automotive, food, medicine and other industries for color quality control and color difference detection.



Colorimeter calibration is indispensable for reliable quality control—ensuring measurement accuracy by compensating for component aging, environmental interference, and baseline drift. It standardizes data across devices/batches, maintains compliance with industry standards, and prevents costly rework from inaccurate color readings, making it critical for precision-driven industries like printing, food, plastics, textiles, paint and coatings.
