Product Introduction
I.CGM6812-B00Description of Combustible Gas Sensor Pre-calibrated Module:
Combustible Gas Sensor Pre-calibrated ModuleCGM6812-B00 is a new module equipped with Figaro catalytic combustion typecombustible gas sensorTGS6812, featuring excellent durability and high stability. This module provides an analog voltage output proportional to hydrogen concentration. The CGM6812-B00 module also features a moisture-proof coating, allowing reliable use in environments requiring waterproofing and insulation. Additionally, the module can detect sensor disconnection faults. The module operates over a wide temperature range of -10°C to +60°C. Since the TGS6812 gas sensor can detect methane, LP gas, and hydrogen, this module is suitable for leak detection of hydrogen, a combustible gas, in stationary fuel cells.
