Remote monitoring device AVUS-COMBI

Safe Smart City

Appointment

Displaying the data coming from the connected gas detectors AVUS-COMBI (modifications with the RS-485 interface) which monitor the concentration of combustible gases (methane and propane) and carbon monoxide.

Application

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.
