ST001D LCD whiteness tester
ST001D liquid crystal whiteness tester is widely used in the fields of medicine and food, flour, starch, paper making, printing, textile printing and dyeing, ceramic enamel, building materials, chemical industry, salt making and so on. It is used to measure the whiteness of objects, and can also measure the opacity, transparency, light scattering coefficient, light absorption coefficient and ink absorption value of paper.
This instrument can measure the whiteness of building materials and nonmetallic mineral products.
Hunter whiteness WH can also be determined.
●Measure ISO Brightness (R457 Brightness), which can also be used to measure the fluorescence whitening of samples that emit fluorescent substances.
●Measure the brightness stimulus value.
●Measure opacity.
●Measure transparency.
●Measure the light scattering coefficient and absorption coefficient.
●Measure the whiteness of blue light.
●This instrument adds a printer and adopts imported thermal printing movement, without using ink and ribbon, without noise when working, and with fast printing speed.
●The instrument has memory function.
●Even if the power is off for a long time, the memory zero, calibration, standard sample and reference sample value and other useful information will not be lost.
Main performance characteristics
●The instrument simulates D65 illumination.
●The instrument adopts d/o illumination to observe geometric conditions. The diameter of the diffuse sphere is 150mm, and the diameter of the test hole is 30mm. It is equipped with a light absorber to eliminate the influence of specular reflection of the sample.
●The instrument adopts a large screen high pixel LCD display module, which displays measurement and statistical results in Chinese and prompts operation steps.
●The user-friendly human-machine interface makes instrument operation simple and convenient.
●The instrument has added a printer and adopts imported thermal sensitive printer cores, which do not require the use of ink and ribbons, have no noise during operation, and have fast printing speed.
●The instrument has power outage protection, and calibration data will not be lost after power outage.
Main technical parameters:
●Simulate D65 illumination.
●Adopt d/o illumination observation geometric conditions.
●The diffuse ball is 150mm in diameter and the measuring hole is 25mm in diameter. It is equipped with an optical absorber to eliminate the influence of mirror reflection on the sample.
