HOW THE PRODUCT WORKS
Hydrogen measurement for demanding process conditions
The PDM300 Industrial-Grade Hydrogen Concentration Sensor uses the selective hydrogen response of a palladium-alloy thin film for in-line measurement in demanding process environments. It is designed for applications that need hydrogen detection in oxygen-free gas or high-humidity conditions, including saturated water vapor. The manufacturer states that condensate does not affect operation.
With a configurable measuring range up to 0–100% Vol, response time under 30 seconds, and both RS-485 and 4–20 mA outputs, the PDM300 can be integrated into hydrogen production, gas blending, and fuel-cell monitoring systems. Confirm the required range, electrical interface, gas composition, and installation conditions for your project before ordering. This helps assess the PDM300 for high-humidity industrial hydrogen concentration measurement.
