Glossmeter principle

(English: Gloss Meter), also known as gloss machine, light meter, light meter, gloss meter, gloss meter, gloss tester, gloss tester, glossmeter and smoothness tester are measuring objects Special instrument for surface gloss. Widely used in chemical raw materials, paint manufacturing, aerospace industry, automotive industry, shipbuilding industry, electronics industry, electrical appliance industry, IT communications and other supporting special measuring instruments. (Glossiness instrument unit No. 2 "GU"). The 213 gloss meter is a 213 switch to the mirror 213 mode in the portable gloss meter to make the instrument widely used.
The light source emits a beam of light that reaches the measured surface P through the lens L1. The measured surface reflects the light to the lens L2. The lens L2 converges the light beam to the photovoltaic cell located at the light barrier B. After the photovoltaic cell undergoes photoelectric conversion, the electrical signal is sent to The processing circuit performs processing, and then the instrument displays the measurement results. It should be noted that during the entire gloss measurement process, the light from the default light source is very stable and will not change.Glossiness is completely different from the concept of "smoothness" or "roughness" in the mechanical processing industry, which is an evaluation of the small unevenness of the material surface.The measurement principle of the gloss meter [1], the light source G emits a beam of light through the lens L1 to reach the measured surface P, the measured surface P reflects the light to the lens L2, the lens L2 converges the light beam to the photocell located at the light bar B, After the photoelectric conversion of the photocell, the electrical signal is sent to the processing circuit for processing, and then the instrument displays the measurement result. As for the unit of glossiness, according to JIS regulations, the unit of glossiness may be% or number. In addition, when recording, in principle, the manufacturer name and model of the measuring angle measuring instrument should be specified.
