GMS4000 Multi-Gas Detector Concentration Leakage Measurements in Pipelines

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.


GMS4000 Multi-Gas Detector 

The user is offered maximum maintenance friendliness and maximum availability because the intelligent measuring sensors can be quickly exchanged if necessary without configuration problems. Thanks to the menu navigation in conjunction with the automatic measuring range selection, the GMS 4000 measuring system can be operated easily and safely at any time, even by inexperienced users. All that is required for commissioning is a task in the main menu, e.g. Gas detection, to be selected, and the measuring device then automatically sets sensor selection, measuring range, pump output and alarm message according to a defined program.
