Introduction
DS-100 Spectrophotometer is a portable Spectrophotometer developed by using independent Spectrophotometer core technology, which is a high-level Colorimeter under the spectroscopic architecture, which not only ensures the accurate relative value ΔE, but also ensures the accuracy of the absolute value L, A and B for a long time, and can pass the measurement of international standards and national standards anytime and anywhere. Using built-in silicon photodiode array (double row 24 groups) sensor, imported whiteboard, the repeatability of ΔE*ab can be easily controlled within 0.1, while taking into account the measurement speed and convenience of operation, and the color difference measurement judgment can be quickly carried out without connecting to a computer or software.
Applications
DS-100 Spectrophotometer is equipped with 8mm measuring aperture, which can meet the precise color difference control in the production and quality inspection of various industries such as plastics and electronics, paints and inks, textiles and garments, printing and dyeing, printing, ceramics and other industries.
Technological advantages
1. Ergonomic design
DS-100 Spectrophotometer has a beautiful, smooth shape and comfortable grip, ergonomic structure design, fit in the palm of the hand for continuous detection work, so that you can use it quickly and easily.
2. Adopt full-band balanced LED light source
The all-band balanced LED light source ensures sufficient spectral distribution in the visible light range, avoids the spectral loss of white LEDs in a specific wavelength band, and ensures the measurement speed of the instrument and the accuracy of the measurement results.

3. Silicon photodiode array (dual 24 array) sensor
The larger area of the dual 24 array sensor, strong light will not be saturated, low light sensitivity is higher and the spectral response range is wider, which ensures the measurement speed, accuracy, stability and consistency of the instrument.
4. Metrological verification report
Each DS-100 spectrophotographic Colorimeter has been verified and tested according to the measurement standards of the credible verification department, and the measurement data can be traced back to the National Metrology Institute to ensure the credibility of the instrument test data.
5. ETC real-time calibration technology
DS-100 Spectrophotometer adopts imported standard whiteboard, which is resistant to yellowing, dirt does not penetrate, and can be wiped, which ensures the long-term accuracy of the instrument. At the same time, it also adopts the innovative ETC real-time calibration technology (Every Test Calibration), and the optical system has a built-in standard whiteboard, which has reliable accuracy and repeatability in every test.
