CMT76 wall-mounted carbon monoxide transmitter uses electrochemical principle to detect carbon monoxide in the air, with good selectivity and stability. Three output modes of current, voltage and RS485 are optional, wide voltage power supply and power supply ant-reverse connection protection. It is suitable for carbon monoxide gas monitoring in indoor air quality detection, air conditioners, air purifiers, underground parking lots and other occasions.
Multiple signal output types, suitable for various processing equipment
Up to 5 years of service life
The protection level is IP6X
