KQ500 gas alarm system consists of KQ500 gas alarm controller and gas detector. This system can connect many detectors to detect different kinds of gases and monitor the gases in the distance.
KQ500 gas alarm system applies to petroleum prospecting, oil and gas
transmission, refinery, metallurgy, power plant, chemical industry, oil depot,
liquefied gas station, mines, tunnels, and underground pipeline.

KQ500 gas alarm controller collects 4-20 mA signal from detector, and transfers the signal into digital signal. After internal SCM data processing, LCD screen shows corresponding gas concentration and output control signals.
KQ500 gas alarm controller is easy to be installed. It realizes measurement, displaying, and public alarm control for 4 channel, 6 channel or 8 channel physical quantity. When the concentration of detected gas reaches or exceeds the preset alarming value, controller will send out audible and visual alarm immediately to remind you take safety precautions (start exhaust, control system) to avoid explosion, fire and toxics.
