TCM101-H2 Hydrogen Purity Sensor
Compact hydrogen concentration sensing for hydrogen leak monitoring, integrated equipment, and industrial hydrogen applications.

Overview
The TCM101-H2 is a compact hydrogen purity sensor independently designed and developed by our team. It uses a MEMS-based miniature thermal conductivity sensor to measure single hydrogen concentration through the thermal conductivity relationship of binary mixed gases. It is widely suited for hydrogen generators, hydrogen refueling stations, compressors, energy storage, and industrial production environments where compact hydrogen leak monitoring is needed.
