GRI-8522Wall-mounted CO2 Detective Alarm 

Product Introduction 

    GRI-8522 series single point wall-mounted CO2 detective alarm is an apparatus which can continuously detect CH2O concentration in operate environment .can online monitor the concentration of CO2.

    The single point wall-mounted CO2 detective alarm is natural diffused gas detective way, adopt America imported 6004 infrared detective module as the sensitive component, with high sensitivity and excellent repeatability; Highlight LED backlit plus LCD display screen real-time display the concentration of leakage gas , Exceed pre-set alarm point immediately start sound and light signals and replay control signals; international standard 4-20mA signal can directly connect DCS system of factory ,connect RS485 digital signal and factory PC .

Product Feature 

imported NDIR infrared module ,performance stable and reliable ;
