Is an ideal instrument for updating the trace moisture tester.
The automatic micro-moisture meter is an automatic coulometric titrator which uses double platinum as an indicating electrode according to Faraday's law. The principle of the instrument for measuring moisture is as follows: when a water-containing sample enters the electrolyte containing constant iodine, the iodine in the electrolyte is consumed, the change of the iodine content is detected by the measuring electrode, and the iodine is separated out from the anode of the electrolytic electrode to supplement the iodine consumed by water. The mole number of iodine in the whole reaction process is equal to that of water, so that the real water content in the tested sample can be directly displayed on a screen by automatic treatment of the instrument.
