Measurement Principle
The measuring principle of the light transmittance meter is to irradiate the measured transparent substance with a light source, and the sensor respectively detects the incident light intensity of the light source and the light intensity after passing through the measured substance, and the ratio of the transmitted light intensity to the incident light intensity is light transmission. Rate, expressed as a percentage.

Product description:
* The three-channel model combines three kinds of light transmittance : visible light, infrared light and ultraviolet light.
* It can be applied to measure the transmittance or haze of all kinds of transparent, translucent samples with parallel plane.

Features
* The instrument has automatic calibration and manual calibration function. It automatically calibrates to 100% transmittance after power on. When performing manual calibration operation, the LCD displays prompt information in time, and the operation is simple and clear.
* This Window Tint Meter is a hand held device that measures the amount of light that passes through a window.
* Technology is designed in accordance with GB 2410-80, ASTM D1033-61, JIS k7105-81 and other standards.
* Digital display, wide measurement range, high resolution.
* Single / Continuous measuring mode.
