Refractometer, also known as refractometer, is an instrument that uses light to test the concentration of liquids. It is used to measure the refractive index, birefringence, and optical properties. The refractive index is one of the important physical constants of substances. The digital refractometer can collect signals, convert various changes into electrical signal changes, and amplify the collected signals. corresponding digital signal. The decoding display circuit converts the digital signal into a signal that the display can recognize, and is connected to the digital display circuit.
The precautions for use are as follows:
1. Do not expose this instrument to low temperature, high temperature and sunshine environment, to prevent the liquid crystal display from losing its function, and prohibit any violent collision.
2. In order to prevent its damage, please do not disassemble or replace its internal components at will, and please do not use this instrument in a humid and corrosive environment.
3. Clean the prism face and prism table window before and after each measurement.
4. In order to prevent the distortion of the measurement results due to the volatilization of the solution, please measure immediately after the solution is dripped.
5. If the voltage is not enough, the measurement result may be distorted.
6. Prevent liquid from entering the battery case.
