QED Environmental Systems
Landfill & Environmental Gas Monitoring – GEM Pro and SEM5000
Effective landfill gas management requires reliable data from both the gas extraction system and the surrounding environment.
QED provides two complementary instruments for these tasks. The GEM Pro analyzer supports landfill gas well balancing and gas field management, while the SEM5000 enables fast and accurate detection of methane surface emissions.
Together, these instruments help operators maintain regulatory compliance, optimize gas extraction and document environmental performance.
Through Norsk Analyse, the systems are configured and supported for landfill operators, environmental consultants and regulatory monitoring applications.

Two Instruments for Complete Landfill Gas Monitoring
Landfill gas management typically requires two types of measurements: monitoring gas extraction wells and detecting methane emissions across the landfill surface.
QED provides dedicated instruments for both tasks.
GEM Pro – Landfill Gas Analyzer for Well Monitoring and Balancing
The GEM Pro is a modular landfill gas analyzer designed for daily field operation.
The instrument measures methane, carbon dioxide, oxygen and several optional trace gases while also recording pressure and flow conditions. This allows operators to monitor gas wells, balance extraction systems and optimise landfill gas recovery.
Its modular architecture allows gas sensor modules to be replaced or upgraded directly in the field, reducing service downtime and maintaining calibration compliance.
SEM5000 – Surface Methane Emissions Monitor
The SEM5000 is designed for detecting methane emissions across landfill surfaces and infrastructure.
Using laser-based Tunable Diode Laser Absorption Spectroscopy (TDLAS), the instrument selectively measures methane without cross-gas interference. This allows operators to detect and quantify leaks quickly and accurately during emissions surveys.
Integrated GPS and data logging support regulatory reporting and environmental compliance documentation.
Typical Applications in Environmental Monitoring
Landfill and emissions monitoring instruments are used across environmental and waste management operations:
- Landfill gas well monitoring and balancing
- Methane emissions surveys across landfill surfaces
- Environmental compliance reporting
- Gas extraction optimisation
- Leak detection around landfill infrastructure
These measurements support both operational efficiency and regulatory requirements.
Benefits for Landfill Operators and Environmental Consultants
With QED landfill monitoring solutions, you gain:
- Accurate measurement of landfill gas composition
- Reliable detection of methane emissions and leaks
- Improved gas extraction efficiency
- Reduced environmental impact through early leak detection
- Documented compliance with emissions regulations
- Portable instruments designed for field conditions
Together, these instruments support safer and more efficient landfill gas management.
Environmental Monitoring Supported by Norsk Analyse
