▎Product Introduction ：
The PDM300 Hydrogen Sensor utilizes the exclusive selectivity of palladium alloy for hydrogen, enabling reliable hydrogen detection under various complex operating conditions. This sensor offers superior performance including excellent selectivity, immunity to cross-interference, oxygen-independent operation, and extended service life. Its unique technological advantages are further demonstrated by the ability to accurately and reliably detect hydrogen in saturated water vapor environments, with operation unaffected by condensate.
The PDM300 Hydrogen Sensor is widely applicable in multiple scenarios including: online hydrogen monitoring in water electrolysis for hydrogen/oxygen production, online hydrogen purity monitoring in industrial hydrogen-natural gas blending systems, exhaust hydrogen concentration monitoring in fuel cell systems, and hydrogen concentration detection in anaerobic chambers.
▎Key Features ：
1.Full-range detection (0–100)% Vol.
2.High-temperature resistance up to 120°C.
3.High-humidity resistance at 100% RH.
4.Cross-interference free.
5.Hydrogen detection in oxygen-free environments.
6.Service life up to 10 years.
