Overview
The QED GEM PRO is a modular landfill gas analyzer that lets operators replace or add pre-calibrated gas sensor modules in-house or in the field, eliminating factory-return delays. A high-definition touchscreen and GAMSoft software streamline gas well field surveys, and a swappable battery pack keeps the unit running all day.
Working Principle
Individually calibrated, field-swappable gas modules feed a central touchscreen controller that records static, differential and system pressures alongside up to seven gas concentrations, calculating gas flow and heat value while GPS-tagging each well reading for compliance and gas-field balancing.
Applications
Benefits
- No back-to-base service required to replace gas modules
- Each module ships with its own calibration certificate
- Real-time gas field adjustments and effective borehole management
- Longer field operation between charges with hot-swappable battery
- Over-the-air firmware updates via GAMSoft
