GRI-8523 Wall-mounted VOC Detective Alarm 

Product Introduction ： 

 GRI-8523 series single point wall-mounted VOC detective alarm is an apparatus which can continuously detect various volatile gas (VOC) and the gas concentration of lonization potentials ≤10.6eV in operate environment . 
 The  VOC detective alarm is natural diffused gas detective way, adopt America Baseline-MOCON imported PID photoionization 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 ;
    Provide LCD display and sound and light alarm , Full-featured;
    Intelligent design , zero , alarm setting ,calibration is very convenient ;
    Two alarm replays can output control signal for use to drive fans and other equipment;
    Apparatus DC9-24V wide range power supply (use power adapter can connect AC 220V),can be          use once connect the power supply ;
    Metal shell, robust and reliable ;
    Infrared remote control ,more convenient for setting ,modifying the parameters of apparatus;
    Have standard 4-20mA current signal and RS485 digital signal output;

Application:

    Personal safety protection of dangerous places, environmental protection monitoring, industrial safety monitoring, detection of dangerous substances.
