Test your Samples for Accurate Color with the ST50 Spectrophotometer

ST50 a precise, visual instrument for rapid and accurate testing for color. 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.

FAQs About Spectrophotometer

Colorimeters or spectrophotometers are used to measure liquid color. They measure light coming through or reflecting off the liquid. Readings can be reported as Lab*, RGB, or absorbance units. So that objective color analysis can be used to control quality, or to measure chemical concentration.
