Amphenol SGX Sensortech MP7217 Miniature Catalytic Combustible Gas Sensor

Amphenol SGX Sensortech MP7217-DA Miniature Catalytic Combustible Gas Sensor is a low-power, poison-resistant, and robust device in a certified flameproof enclosure. This small-size pellistor is primarily optimized for methane response for up to 5% of volume in air and can detect other flammable gases and vapors. The silicon pellistor offers a low orientation effect and high resistance to mechanical shocks and is assessed as intrinsically safe. Amphenol SGX Sensortech MP7217-DA Miniature Catalytic Combustible Gas Sensor is ATEX and IECEx certified and ideal for use in battery operations and mining applications.
