The AirWatch is your safe area solution for the monitoring of various gases. Based on the measurement values and alarms, equipment is switched on or off, data is logged and optionally employees are remotely informed of the gas concentrations present.
The AirWatch is a safe area monitor with pump, controller, alarm and switch. It can switch on a wide variety of equipment in the event of a gas alarm, from generators to breathing air units and power supplies. With the optional wireless function, you can also view monitor several AirWatches. The data is stored on the PC/laptop or on an SD card in the device itself, with real-time information giving a clear picture of the different locations. Many configurations are possible, so the AirWatch can be used very flexibly, either in standalone mode or as part of a complete system.
