The method of testing the conductance of this instrument is to add the AC voltage generated by the oscillator to the electrode _ (the purpose of adding the AC voltage is to avoid the polarization of the electrode), and a current is generated in the conductivity cell. The conductivity is proportional to the current-voltage conversion, amplification, detection, converted to DC voltage, through temperature compensation, etc., and finally converted into a digital signal by the A/D converter, and displayed by the microcomputer. The entire process is controlled and processed by a microcomputer. Mainly used to measure the conductivity of various liquids. When equipped with an electrode of 0.1 specification constant, the conductivity of pure water or high-purity water can be measured. It can be widely used in light industry, chemical industry, food, medicine, health, energy, environmental protection and education and scientific research department].
