Gas detector AVUS-COMBI

Generating alarm signals about exceeding the specified values of pre-explosive concentrations of methane (propane) or mass concentration of carbon monoxide. Generating a signal to engage the output relay or close the gas shut-off valve.

Monitoring and notification of exceeding specified threshold values of monitored gases in residential and administrative buildings, industrial and industrial buildings, in garages, in car parks and parking lots, etc.
