Audited Supplier 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.
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.
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.
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.
5. Non-contact automatic calibration, professional imported white board, more wear-resistant, dirty, stable
6. Place the base safely to ensure that the whiteboard is not dirty.
7. Offer 8 kinds of color measurement space and 41 kinds of observation light source
Offer CIE LAB,XYZ,Yxy,LCh,CIE LUV, S-RGB, βxy, Munsell(C/2) color spaces, and D65, A, C, D50, D55, D75, F1, F2(CWF), F3, F4, F5, F6, F7(DLF), F8, F9, F10(TPL5), F11(TL84), F12(TL83/U30), B, U35, NBF, ID50, ID65, LED-B1, LED-B2, LED-B3, LED-B4, LED-B5, LED-BH1, LED-RGB1, LED-V1, LED-V2, LED-C2, LED-C3, LED-C5.
