KENTA Split Whiteness Meter

Product Application:
Whiteness meter is mainly used for direct measurement of surface smoothness of the object or powder whiteness value. It can be widely used in the measurement of whiteness of textile printing and dyeing, paint, chemical building materials, paperboard, plastic products, white cement, ceramics, enamel, talc, starch, flour, salt, detergent and cosmetics.

Features:
It consists of light source, optical system, detection system, data processing and display system, the instrument's whiteness formula for the blue light whiteness R457.
Define the complete diffuse reflector in the visible spectrum within the diffuse reflectance ratio of 1 is the ideal surface of the whiteness value of 100, the spectral reflection factor of 0 on the black surface of the whiteness of 0.
The use of high-quality imported components, good reliability.
Reasonable, simple optical design, the use of modified filter system, can quantify the whitening value after fluorescent whitening.
No warm-up after starting, simple calibration can be measured, easy to operate.
Through rigorous testing, commissioning, the instrument complies with the JJG 512- 2002 Whiteness Meter Verification Regulation, which complies with GB3978, GB3979, GB7973, GB7974, ISO2470, GB8904. 2, QB1840, GB2913, GB13025. 2, GB1543, ISO2471, GB10339, GB5950, GB12911, GB2409 and other standards.
Can store 254 sets of data.
Using USB, RS-232C data line output and PC connection, for data collection.
There is also Bluetooth Bluetooth data output to provide a choice.

Working principle:
The instrument is composed of light source, optical system, detection system, data processing and display system. The whiteness formula of this instrument is blue light whiteness R457. The whiteness value of the ideal surface with a diffuse reflectance ratio of 1 in the diffuse reflector is 100 and the whiteness of the black surface with the spectral reflection factor of 0 is zero. The instrument's light source uses 457nm long-life LED. The instrument receives the principle of photoelectric effect. By the photocell to receive the sample surface diffuse reflectance of the radiant energy value, the high-precision automatic zero-stability after amplification of the amplifier, the input to the calibration circuit for energy value calibration, and then by the digital display directly shows the sample whiteness value.
