HY-GA40A is a device designed for continuous monitoring of the presence of natural gas in the airMicroprocessor-based digital gas detectors are distinguished by high sensitivity and stable performance, fast response time and low level of false alarms
Exceeding the threshold gas concentration is signaled optically and acousticallyDetector control outputs enable connection of an external fan and a gas access shut-off valveThe detectors are designed to work as part of the alarm system
