Sell intelligent CO detect transmitter

Description

intelligent  carbon monoxide sensor transmitter provides ***0 mA output and ModBus RTU output proportional to the carbon monoxide concentration and has LED(LCD optional) digital display real-time CO concentration. Its RS**5 digital signal is for communication. It easy to operate, reliable and has full functions, making it a leader in the nation. It has been widely used in petrol, chemistry, metallurgy, artifice, gas transportation, biological medicine and water procession etc.
Sensor types: electrochemical sensor; Catalytic sensor; infra-red (IR), Photo Ionization Detection.
***0mA analog output(3+ channel) for direct communication to DCS system and RS**5 ModBus output.
Sensor module design on -spot replacement s and automatically distinguish sensor fault and current display fault simultaneously.
