Product Desciption

Brightness and Color Tester

YT-48A Brightness and Color Tester is the first new automatic one-button measurement of all color and whiteness technical parameters in the industry developed by the company. It is widely used in paper-making, printing, textile printing and dyeing, ceramics, building materials, chemicals, food, salt production and other industries and other production and commodity inspection departments that need to determine the color and whiteness of objects.

Product Features

Large screen and high pixel liquid crystal display module,display and

prompt the operation steps to display measurement and statistical results,friendly man-machine interface makes the instrument easy to operate

Increase data cache, which is convenient for users to back up, review, and compare historical data. It can store up to ten reference information.
The instrument has a power-off protection function, and the calibration data will not be lost after power-off.
can be measured multiple times and gives the arithmetic mean of a series of measurements
Measure the color of the object, report the diffuse reflection factor Rx, Ry, Rz, stimulus value X10, Y10, Z10, chromaticity coordinates x10, y10, brightness L*, chromaticity a*, b*, chroma C*ab, hue Angle h*ab, dominant wavelength λd, excitation purity Pe, color difference ΔE*ab, brightness difference ΔL*, chroma difference ΔC*ab, hue difference ΔH*ab, Hunter system L, a, b
Using thermal printer core, no need to use ink and ribbon, no noise when working, fast printing speed, etc
This instrument is equipped with standard RS232 interface, which can be used with PC software for communication (optional)
