PROFESSIONAL LANDFILL GAS MANAGEMENT WITH INTELLIGENT MODULAR DESIGN
The Geotech GEM PRO is the only gas extraction instrument which lets users replace or add gas modules in the field. Users now have the choice to service their instrument with pre-calibrated gas cells or to send their instrument to the factory for a full inspection and calibration. A high-definition touch screen and professional GAMSoft software make collecting and uploading easier with fewer errors. Gas technicians can quickly survey and tune a gas field, knowing that they have all-day battery capacity with the industry's only hot-swappable battery pack. The GEM PRO is truly revolutionising your gas extraction monitoring instruments.
Intelligent, factory calibrated and user replaceable modules for the measurement of gas or pressure
