PDM300 Industrial Hydrogen Concentration Sensor
Industrial hydrogen concentration sensing for online process monitoring in complex, high-temperature, high-humidity, and oxygen-free hydrogen environments.
Overview
The PDM300 industrial hydrogen concentration sensor uses the strong hydrogen selectivity of palladium alloy to enable hydrogen detection under complex industrial process conditions. It offers good selectivity, no cross-interference, no need for oxygen to participate in the sensing reaction, and long service life. Its technical advantage is especially strong in harsh process environments, because it can detect hydrogen accurately and reliably in saturated water vapor, is not affected by condensed water, and can even tolerate liquid water immersion.
