Spectral spectrophotometer

YT-CM3000Spectral spectrophotometer

Spectral spectrophotometerIt is a precision instrument for measuring the whiteness and color of solids, widely used in industries such as papermaking, printing, textile printing and dyeing, ceramics, building materials, chemical industry, grain, salt production, and other production and inspection departments that need to measure the color and whiteness of solids.

Product Features

1. Imported concave flat field gratings, photoelectric display sensors, pulse xenon lamps and other components are used to ensure the accuracy of the equipment. The circuit adopts an ARM+FPGA dual core scheme to ensure computing power and sampling timing accuracy.

2. By using a stepper motor to control the ultraviolet radiation level, automatic and precise control of the radiation level has been achieved, eliminating the need for manual pull plate structures and enabling one click testing of fluorescence brightness.

3. The instrument is operated using PC software, and the storage space for test data is not limited; Convenient access and printing of historical measurement data, with no limit on the number of standard samples; If the manufacturer's software features are added, users can easily update them
