WSB-V into the flour whiteness meter intelligent whiteness tester - Zhengzhou Grain Machinery Factory
Model: WSB-V
Product introduction:
Using the new semiconductor light source technology, service life of up to 100 thousand hours (from your replacement and maintenance troubles), instrument without heating, 24 hours of continuous operation, energy saving and environmental protection, automatic calibration, instrument stability, reliability and life of the light source and other indicators have been greatly improved. The instrument is used to measure the surface of Portland Guangbai, technical performance in line with JB/T9327-1999 whiteness meter standard, determination results of digital display, can also be the printer to print out the data (printer options by the user according to the needs of its own choice), simple operation, high precision. Applicable to product whiteness determination in flour, starch, Rice noodles, salt, textile, printing and dyeing, chemical fiber, plastic, porcelain clay, talcum powder, white cement, paint, paint, enamel, ceramics, paper and pulp industries such as the Department of.
Working principle:
Integral ball measure juedui spectral diffuse reflectance using optical instruments, the principle is the use of semiconductor light source emits blue light directly into the integrating sphere, the blue light in the inner surface of integrating sphere diffuse reflection, in the test samples and irradiation, the spectral reflectance of the sample surface through the condenser, light bar, filter group the photocell is converted into electrical signals; otherwise a battery Guiguang sphere signal receiving substrate. The two electrical signals are amplified individually and processed by single chip microcomputer to achieve automatic zero calibration, whiteboard calibration and sample testing. The user can use this instrument to test whiteness of various samples very simply.
Technical parameters:
1. The vertical detection method of diffuse illumination (d/o). This instrument complies with GB3978-83 standard illumination and lighting conditions, simulation of D65 lighting lighting, using d/o lighting and observation geometry, diffuse ball diameter 120mm, diameter measuring hole 20mm, a light absorber, eliminating the effect of specular reflection.
