DS-700D spectrophotometer has good interstage difference and repeatability, and the measurement data is accurate and reliable. It adopts 400-700nm full wavelength LED light source and is equipped with 3 kinds of measurement apertures, which can meet the measurement of various samples. It not only supports connecting to computer to process data, but also supports Android, ios and WeChat applet, and data can be stored anywhere and anytime.

Smart Auto Calibration

Equipped with three measuring calibers, no tools required, change at any time

Provide 30+ measurement parameters and 37 evaluation light sources

Support Android, IOS, WeChat applet, Windows program

Camera framing positioning, can clearly observe the measured area

Excellent repeatability and inter-stage difference

Repeatability ΔE*ab≤0.025, difference between units≤0.25, accurate and reliable data, ensuring the consistency of measurement data from multiple devices for color matching and accurate color transfer

Dual-column high-precision CMOS array design monitors the energy fluctuation of the light source while measuring the sample signal to reduce interference during measurement and obtain higher measurement stability. Large-area dual-array sensor provides higher spectral response sensitivity, ensuring high standards of instrument measurement speed, accuracy, stability and consistency of inter-stage differences

 

Automatic Calibration Technology

The instrument is placed on an intelligent calibration base, and the instrument can be automatically calibrated by the whiteboard on the base without human intervention. It changes the status quo of traditional instruments that must be calibrated manually on the white board. The white board made of ZrO2 with reflectivity R%>90% is used as the calibration standard, which ensures good mechanical strength and weather resistance, and no scratches and discoloration will occur in long-term use

 

Spectral technology to ensure the accuracy of the measurement

The instrument uses a full-band balanced LED light source and UV light source as the illumination source, ensuring sufficient spectral distribution in the visible and UV bands, and materials containing fluorescent components can also be measured
The combination of a grating and an array sensor made by an innovative MEMS process allows for more accurate color measurement based on a 10 nm spectral resolution

 

Combination of various performance, better use

Equipped with three measuring calipers, which can be replaced at any time without tools to meet the needs of various sample measurements

Provide a variety of measurement parameters and evaluation light sources in accordance with international standards Flexible to add various light sources and measurement indexes through mobile terminal or PC terminal program

Support Android, IOS, WeChat applet, Windows program

Camera view positioning, can clearly observe the measured area
