Spectrophotometer ST70 is a spectrophotometer developed by 3NH TS series core technology, using built-in photodiode array (double 32 groups) sensors, imported whiteboard, while taking into account the measurement speed and convenience of operation. The repeatability delta E* AB of ST70 spectrophotometer is easily controlled within 0.02, and the Inter-instrument error delta E* AB is controlled within 0.15, to make the measurement more accurate. And the test data can be used for accurate color analysis and transmission in the laboratory.
1. Adopt full waveband balanced LED light source
The full waveband balanced LED light source ensures sufficient spectral distribution in the visible light range, avoids the spectral loss of white LED in specific waveband, and ensures the measurement speed and accuracy of the measurement results.
2. Place the base safely to ensure that the whiteboard is not dirty.
3. Professional whiteboard, a lifetime never change color commitment
4. Fast charging
5. Equipped with three measuring apertures to meet the most samples measurement
The Factory configuration of spectrophotometer ST70 is with ø 8mm flat aperture, ø 8mm tip aperture, ø 4mm flat aperture, ø 4mm tip aperture, ø 1x3mm aperture, a total of five measuring apertures, to meet the most samples measurement.
6. Camera positioning can clearly observe the measured area
Spectrophotometer TS7708 built-in camera positioning, through the camera real-time view, can accurately determine whether the object measured part is the target center, improve the measurement efficiency and accuracy.
7. Excellent errors between instruments and repeatability
Ensure the consistency of measurement data of multiple equipment, to be used for color matching and accurate color transfer.
8. Offer 10 kinds of color measurement space and 41 kinds of observation light source
Offer CIE LAB,XYZ,Yxy,LCh,CIE LUV, S-RGB, HunterLab, βxy, DIN Lab99, 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. It also can be customized light source (A total of 41 kinds of light source, Partially realize through the PC software /APP software), and can meet the special measurement requirements under different measurement conditions.
9. Many color indexes
Spectrophotometer ST70 not only provides the commonly used color measurement, but also provide spectral reflectance, WI (ASTM E313, CIE/ISO, AATCC, Hunter, TaubeBergerStensby), YI (ASTM D1925, ASTM 313), Metamerism index of Mt, Staining Fastness, Color Fastness, Color Strength, Opacity, 8 degree gloss, 555 tone classification, Carbon (My,dM), color density CMYK(A,T,E,M), Tint, Munsel chroma index (part of the function is realized by PC software).
