Product Presentation

The twin sister ST series of 3NH TS series is launched grandly, inherits the core technology of large-area array sensor and grating splitting in the field of color detection, and acutely analyzes the strong and weak light in 300-1100nm band. Our TS series has always been imitated, but never surpassed. TS series since its birth has been adhering to the quality first, with the purpose of quality, after years of continuous improvement, we can proudly say: ST series, let the color measurement is very accurate! In the future, 3nh will continue to practice the mission of "specialized and innovation" enterprise and high-tech enterprise, overcome difficulties and continue to innovate on the road of testing instruments, so that our partners can have a wonderful high accuracy and quality measurement instrument.


Spectrophotometer ST50 is a spectrophotometer developed by 3NH TS series core technology, using built-in photodiode array (double 20 groups) sensors, imported whiteboard, while taking into account the measurement speed and convenience of operation. The repeatability delta E* AB of ST50 spectrophotometer is easily controlled within 0.03, and the Inter-instrument error delta E* AB is controlled within 0.2, to make the measurement more accurate. And the test data can be used for accurate color analysis and transmission in the laboratory.




Spectrophotometer ST50 is equipped with one customized measuring aperture, accurate color measurement and stable performance. It is used for accurate color measurement and quality control in plastic electronics, paint ink, textile and garment printing and dyeing, printing, ceramics and other industries, and can be used for fluorescent sample measurement.




1. Large area photodiode array (dual 20 arrays) sensor

A larger area of double 20 array sensor, strong light saturation, weak light sensitivity and a wider spectrum response range, to ensure the instrument measurement speed, accuracy, stability and consistency, independent core technology, and international standards of the same platform, to achieve complete compatibility.

Large area photodiode array (dual 20 arrays) sensor

2. Adopt D/8 structure and SCI/SCE mode

Spectrophotometer ST50 uses a widely international use D/8 optical structure, SCI/SCE (Specular Component Included/Specular Component Excluded) synthesis technology, support SCI+SCE at the same time fast measurement, test time about 1.5 seconds.

Adopt D/8 structure and SCI/SCE mode

3. Combination of full spectrum LED light source and UV light source

The use of 400-700nm full spectrum LED light source ensures sufficient spectral distribution in the visible light range, avoiding the spectral loss of specific bands, strong light will not be saturated, weak light is more sensitive, and fluorescence samples can be easily measured.

4. Camera positioning can clearly observe the measured area

The ST50 spectrophotometer has built-in camera. Through the real-time scene-taking of the camera, it can accurately determine whether the measured part of the object is the target center, which improves the measurement efficiency and accuracy.

Camera positioning can clearly observe the measured area

5. Non-contact automatic calibration, professional imported white board, more wear-resistant, dirty, stable
