The HY-GB40A is a device designed for continuous monitoring of LPG (propane) concentration in the air. The MCU-based, digital gas detectors are distinguished by high sensitivity and stable performance, quick response time as well as a low level of false alarms.
Gas concentration above the threshold level triggers visual and audible alarm signals. The control outputs of the detector enable the connection of an external fan and a gas cut-off valve. The detectors are intended to used as part of a security system.
