▎Product Introduction ：
The TCM200 Miniature Hydrogen Concentration Detector 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 0–10% Vol hydrogen leaks.
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: Withstands 100% hydrogen shock with excellent long-term stability.
5.Extended service life: Non-consumptive sensor design ensures up to 10 years of operation.
