JINGKELIAN C84-III reflectivity meter film hiding power measuring instrument

overview

C84-III Reflectance Meter is used to test the hiding power of coatings, inks, pigments and other coatings, and is widely used in the chemical industry. The design of the C84-III reflectance measuring instrument is in full compliance with the relevant provisions of the international standard ISO3906-1980 (E), national standards GB/T13452.3-92, GB9270-88, GB5211.17-88, and the measurement range is 0~100, the repeatability is 0.3%.

Principle

The C84-III reflectance measuring instrument consists of a probe, a main body, a standard plate (one black and one black), a working ceramic plate (two black and white), etc. The specific principle is that the probe adopts the principle of 0° irradiation and diffuse reflection reception. When the reflected light of the sample acts on the surface of the selenium photocell, an electrical signal is input to the DC amplifier for amplification, and the reading is displayed (the schematic diagram of the optical circuit and the block diagram of the instrument are shown below)

Electrical box x1, probe x1, black standard board x1, white standard board x1, black work board x2, white work board x21, spare light bulb x3, mirror cloth x1, Encasement box x1.
