The device innovation GMS 4000 is the universal device for gas leak detection, network control and gas analysis. With infrared measurement technology, the measuring instrument can determine natural gas and CO2 exactly and without cross-sensitivities. The GMS 4000 detects heavy gas, oxygen, hydrogen sulfide and carbon monoxide (optional sensors). In addition, the ethane / propane analysis with data storage of the measurement results is possible.

A Bluetooth interface and a GPS receiver are available. Data storage with the GPS coordinates and the transfer of the data to the PC to document the route are also possible. The device can of course be controlled wirelessly with the tablet PC. With the new lithium-ion batteries, the operating time and reliability of the device are unmatched.

The GMS 4000 is equally suitable for above-ground gas pipe network checking, measurement of gas and ground gas, gas analysis or room air Monitoring. With its infrared measuring technology this measurement instrument can accurately identify natural gas and CO2 without cross-sensitivity.
