Product Description

Product Description

The whiteness tester is used to measure the whiteness of objects, and also to measure the transparency, opacity, light scattering coefficient and absorption coefficient of paper.

Application

1. Determine the diffuse reflection factor of blue light (R457) of the sample, which is called "blue brightness" or "ISO brightness".
2. The paper analyzes whether the sample material contains fluorescent brightener, and can determine the brightness of fluorescence produced by fluorescence emission, that is, whiteness.
3. The intensity stimulus value Y10 of the sample was measured, namely, the diffuse reflection factor ry of green light.
4. The opacity, transparency, light scattering coefficient and light absorption coefficient of the sample were measured.
5. Determine the ink absorption value of paper and board.

Main Features

1. The appearance of this instrument is novel and compact, and the advanced circuit design effectively guarantees the accuracy and stability of the measurement data.
2. Large-screen high-pixel LCD display module, Chinese display and prompt operation steps, display measurement and statistical results, friendly human-machine interface makes the instrument operation simple and convenient.
3. This instrument is equipped with a standard RS232 interface, which can cooperate with computer software for communication.
4. The instrument is protected from power failure, and the calibration data will not be lost after power failure.
5. Can store 10 reference samples (real samples or data).
