Principle of Operation：

Based on Faraday’s Law of Electrolysis, theTM505s sensor absorbs and electrolyzes moisture to fractional parts-per-million (ppm). One hundred percent of the sample moisture is absorbed by a hygroscopic film that covers two spiral wound electrodes embedded in a hollow glass tube. When the sample gas enters the cell at a known flow rate, the phosphorus pentoxide (P2O5) film absorbs all the moisture molecules present. By applying an electrical potential (voltage) to the electrodes, each absorbed water molecule is electrolyzed, generating a finite current. This current is precise and proportional to the amount of absorbed water.

Special features:

• The split design ensures that the gas circuit is completely separated from the circuit and is not affected by chlorine leakage;
• According to the principle of Faraday electrolysis method, a unique double spiral electrolytic cell is manufactured
• The specially formulated coating solution enables complete electrolytic absorption and fast response;
• The specially made P2O5 film is attached evenly and firmly, without loss, and has a long service life;
• The Color touch LCD display, intelligent touch screen operating system;
• Display of multiple humidity units, ℃ (dew point), PPMv, mg/m3
• Intelligent one button operation enables quick and simple measurement;
• With air circuit protection and control system, the measurement results are accurate and reliable, and are not subject to air source pressure
• The influence of force fluctuation;
• The unique control system can realize the rapid measurement and switching of data;
