YJ-2410 Transmittance Haze Meter

This instrument complies with testing standards such as GB/T2410-2008, ASTM D1003-2007, and JIS K7105-81, facilitating technical exchanges both domestically and internationally. It employs parallel illumination, hemispherical scattering, and an integrating sphere photoelectric reception method. Equipped with a microcomputer automatic operating system and data processing system, it features no-knob operation for ease of use and includes a standard USB interface. It automatically displays the average value of multiple measurements for transmittance/haze, with transmittance results displayed directly to 0.1% and haze to 0.01%. There is no zero drift, ensuring strong reliability. A darkroom is used to guarantee the safety of operators handling large samples. It is used for testing the transmittance and haze of all transparent and semi-transparent parallel plane samples (such as plastic plates, sheets, etc.) and for measuring the turbidity or clarity of liquid samples (water, beverages, etc.). The testing principle is that the percentage of luminous flux passing through the sample to the luminous flux incident on the sample is the transmittance; the percentage of scattered luminous flux deviating from the incident light direction through the sample to the transmitted luminous flux is the haze.
