Fixed CO carbon monoxide detector is the safety device for chemical industry and human security. It used for dangerous places to detect co gas and toxic gases anytime. The industrial co detector is a intrinsically safe instruments which continuous operation environment of poisonous and harmful, inflammable and explosive gas concentration. It is suitable for explosion-proof, co gas leak, underground pipelines or mines etc, can effectively ensure the life safety of the staff are not violated, the production equipment from losses.

Features:

* Use high-grade imported micro-processing chip; Processing speed, high precision, reliable operation
* Use calibration, alarm set points, on-site without opening the lid, long life
* 4 ~ 20mA output signal and RS485 interfaces standard digital signal can be connected with the DCS system
* Relay output linkage
* Live disconnection protection, wiring error in the case of the transmitter is not compromised
* Output signal protection, regardless of any fault, can guarantee that no more than 25mA current signal
* Professionally designed mounting bracket, easy installation, fast respond
