First, ten functional characteristics:
1) Repeatability and inter-station difference: Repeatability Max: dE*ab ≤ 0.04, inter-station difference ≤ 0.25
The data is accurate and reliable, ensuring the consistency of measurement data of multiple devices, and can be used for color matching and accurate color transmission. 
 
2) Passed the first-class measurement
3) Dual-path array sensor
The design of double optical path can monitor the fluctuation of light source energy while measuring sample signal, which reduces interference and obtains higher measurement stability. Adopting large-area dual-array sensors, it provides higher spectral response sensitivity, and ensures the high standard of measuring speed, accuracy, stability and consistency between stations.
 
4) Intelligent automatic calibration, the reference is ZrO2 with reflectivity greater than 90%, without frequent whiteboard calibration
The instrument is placed on the intelligent calibration base, and the instrument can be automatically calibrated without manual intervention through the whiteboard on the base. It changes the present situation that traditional instruments must be calibrated by whiteboard manually. The whiteboard made of ZrO2 with reflectivity R% > 90% is used as calibration reference, which ensures excellent mechanical strength and weatherability, and will not scratch or change color after long-term use.
 
5) 360-700nm full-band equalization LED light source and ultraviolet UV light source
The instrument adopts full-band equalized LED light source and UV light source as illumination source, which ensures sufficient spectral distribution in visible and ultraviolet bands, and materials with fluorescent components can also be measured.
 
6) 10nm resolution grating splitting technology
The grating combined with array sensor made by innovative MEMS technology makes color measurement more accurate on the basis of 10nm spectral resolution.
 
7) Equipped with three measuring calibers, without tools, and can be replaced at any time to meet the measurement requirements of various samples
Spectrophotometer DS-700D comes standard with three measuring calibers of 8mm/4mm/1*3mm.
 
8) Providing 30 + kinds of measurement parameters and 37 kinds of evaluation light sources
A variety of measurement parameters and evaluation light sources conforming to international standards are provided. A variety of light sources and measurement indexes can be flexibly added through mobile or PC programs. 9) Support Android, IOS, WeChat applet and Windows program.
 
10) The camera framing positioning can clearly observe the measured area.
