Overview

The German CMC electrolysis method micro water sensor utilizes the principle of electrolyzing water molecules into hydrogen and oxygen. This sensor consists of a glass cylinder and two parallel electrodes, with a thin layer of H3PO4 phosphate film coated between the two electrodes. The electrolysis current appearing between the two electrodes decomposes the water in the acid into H2 and O2, and the final product of this process is P2O5. P2O5 is a highly hygroscopic substance, which absorbs water from the sample gas. Through a continuous electrolysis process, a balance is established between the water content of the sample gas and the water content after electrolysis. The electrolysis current is proportional to the water content of the sample gas.

Product Details

The P2O5 sensor utilizes the principle of electrolyzing water molecules into hydrogen and oxygen. This sensor consists of a glass cylinder and two parallel electrodes. The electrode material is selected according to the specific application (usually made of platinum or rhodium metal wire), and a thin layer of H3PO4 phosphate film is coated between the two electrodes. The electrolysis current that occurs between the two electrodes decomposes the water in the acid into H2 and O2. The final product of this process is P2O5, which is a highly hygroscopic substance. Therefore, it absorbs water from the sample gas and establishes a balance between the water content of the sample gas and the water content after electrolysis through a continuous electrolysis process. The electrolysis current is proportional to the water content of the sample gas, and the signal is amplified and displayed. Data readout. This principle is particularly suitable for measuring trace moisture in high-purity acidic gases such as Cl2, HCl, SO2, H2S, and many other gases (except for a very small number of gases that undergo chemical reactions with phosphoric acid).
