HY4680 Digital Haze Meter is applying to test the light transmittance, transmission haze, and reflection haze, reflectivity of transparent and semitransparent parallel level material and plastic films. Also it is suitable for liquid samples (water, beverage, pharmacy, colored liquid, grease) turbidity measurement. It is the basic instrument for plastic, glass products, all kinds of transparent packaging films, colored and colorless of organic glass and aerospace, automotive glass and photographic film.
Adopt the parallel lighting, hemispherical scattering, and integral ball photoelectric receiving mode. The microcomputer automatic controls test system and data processing system, convenient operation, no knob, and a standard print output pull, automatically display the average value of transmittance/haze repeatedly measured. The transmittance results is up to 0.1%and the haze degree is up to 0.01%. No zero drift, confidence is strong, the specific structure- Open sample window is almost not limited to sample size, fast measurement speed. Due to the adoption of regulated products, instrument is not influenced by the environmental light so it does not need the darkroom; guarantee the safety of operators of large sample.
Electronic circuit of the computerized with high precision, a standard data output interface, supporting the supply remote printer.
★ Microcomputer control, LED digital display, user-friendly fast, intuitive view the test data and results
test light transmittance and haze value in one time, convenient
★ With a professional correction device, haze, light transmittance automatic switching, measurement, calibration
★ Automatic data processing, continuous testing, the average display
★ Equipped with professional process program for different products to ensure reliable test result, automatically finish the process from image capture and test result output;
