CTX10 Combustible Gas Transmitter

ATEXCSADet-Tronics Point IR Termination Box (PIRTB) FM ApprovalIECExSIL 2 Certification

Combine the CTX10 with combustible gas sensors to create a stand-alone gas detector

The model CGS sensor when used with the CTX10 is a catalytic combustible gas detector, provides continuous monitoring of combustible hydrocarbon gas and combustible hydrogen gas concentrations in the range of 0% LFL to 100% LFL. The CTX10 is third-party performance approved for methane and propane gases.
