Gas analyser DG-3-U

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.
