The CMV-2021D Catalytic H2 Hydrogen Gas Sensor is a high-performance catalytic combustion (pellistor) type sensor designed for detecting hydrogen gas (H₂) in industrial environments.
This sensor operates on the catalytic oxidation principle, where hydrogen gas is oxidized on a heated catalytic element, causing a measurable change in resistance. It is especially suitable for detecting high concentrations of hydrogen, including %LEL and % volume levels.
The CMV-2021D is engineered for stability, durability, and fast response, making it ideal for hydrogen leak detection systems, fuel cell infrastructure, hydrogen production facilities, and industrial safety monitoring equipment.
