Product Description

3nh ST50 Spectrophotometer (Core Technology) with one aperture




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.
