Wall-mounted VOC Detective Alarm

Product Introduction ¡y
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 ÿ?0.6eV 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 .
