Gas Detector DГ-3-У for Continuous Monitoring of Carbon Monoxide Levels

Designed for automatic continuous monitoring of the volume fraction of gas and issuing alarms when the maximum permissible concentration of carbon monoxide (CO) in residential, domestic, warehouse and other non-explosive premises equipped with gas burner devices. A set of two AA batteries ensures the operability of the detector in the standby mode for two years! The detector is equipped with a digital display, which shows the following information: - the concentration of carbon monoxide, expressed in ppm (1000 ppm = 0.1%); - the ambient temperature; - the battery voltage; - the state of the output contacts of the fault relay (normally closed or normally open); - the alarm relay threshold. The alarm device has a built-in sound signalling of operation modes.
