▎Product Introduction ：
The TCM101-H₂ Thermal Conductivity Hydrogen Purity Sensor is independently designed and developed by our company. It utilizes a MEMS-based micro thermal conductivity sensor to measure hydrogen concentration through the thermal conductivity relationship of binary gas mixtures. Widely applicable for hydrogen leak monitoring in hydrogen generators, hydrogen refueling stations, compressors, energy storage systems, and industrial production environments.
▎Key Features ：
1.Wide detection range: Capable of detecting hydrogen leaks at concentrations of 0–10% Vol.
2.Compact size: Installable and operable in various confined equipment spaces.
3.Fast response: Enables real-time monitoring of hydrogen concentration changes.
4.High reliability: Features a service life of up to 10 years with excellent long-term stability.
