Nitric oxide transmitter MIC-300-NO

Features of Nitric Oxide Transmitter:


MIC-300-NO Nitric Oxide Transmitter is used to detect the concentration of nitric oxide gas and alarm when the concentration exceeds the limit


It can accurately detect the content of nitric oxide and output a standard signal. The signal is stable. The three-wire or four-wire flameproof wiring method is suitable for various hazardous locations.


Explosion-proof and lightning-proof, anti-static, anti-reverse connection


Anti-EMI, EMC electromagnetic interference


Anti-pulse surge current impact
