### YT1020 940nm & 1400nm Infrared Transmittance Tester
**High-precision portable optical transmittance meter, fast and accurate measurement of transparent material transmittance**

YT1020 uses four light sources for measurement, which can detect **visible light (380nm-760nm), infrared light (940nm & 1400nm peak), infrared full band**, suitable for transmittance analysis of transparent materials such as glass and film. The sensor uses **silicon photodiode**, combined with professional algorithm calibration to ensure measurement speed, accuracy, stability and consistency.

The device automatically calibrates when it starts, and the measurement data can be obtained within **0.5 seconds** after the test material is placed in the measuring slot. It is widely used in **glass, film, optical material** transmittance and shading coefficient analysis.
