The micro moisture meter utilizes the principle of electrolytic detection, and its sensor is made of a cylindrical glass material and two parallel electrodes (usually made of platinum or rhodium metal wire, and the specific material needs to be selected according to the application), with a thin layer of phosphate H coated between the two electrodes₃PO₄The electrolytic current occurring between the two electrodes causes the water in the sample gas to decompose into H₂And O₂The electrode current is proportional to the moisture content in the sample gas, and the instrument processes the current signal in a series of ways to display and output data.It provides an absolute measurement of the trace water content in the sample gas.This principle can be used to directly measure the trace water content in all gases, includingIncluding Cl₂、 HCl、 H₂S、 H₂SO₄、 HBr、 SO₂、 SF₆、 CO₂Wait for gases and all inert gases, except for a few gases that undergo chemical reactions with phosphoric acid.

It is possible to provide sensors with different material casings for different application conditions. The special sensor housing design allows the sample gas to flow through the sensor in a special transmission manner, ensuring rapid sensor response and minimal interference. These designs are suitable for very low ppmLevel measurement is very important.

The electrical connector between the sensor and analyzer is a waterproof sealed structure. Users can easily complete the regeneration of the probe within five minutes.
