1. The light transmittance meter adopts the parallel light path of the light source and the light collecting design of the receiver, so that it can measure large thickness materials. 2. Equipped with a fixed base, with two measurement methods; that is, it is suitable for testing such as on-site measurement of automobile front s, and it is also suitable for fixed-point light transmission measurement such as a fixed station in a factory. 3. Adopt high-resolution acquisition chip, which can realize high-precision data acquisition, fast response and real-time dynamic calibration, high measurement accuracy and fast test speed. 4. The instrument can measure high-transmittance samples. The transmittance measurement range is 0.001% -99.8%, and the highest resolution can reach 0.001%. 5. The 116 light transmittance meter can be used to test the light transmittance of s products, solar films, laminated s, coating materials, organic material panels and other materials. Suitable for display, production, quality inspection, inspection and other occasions.
