The GEM5000 is a portable landfill gas extraction monitor developed to precisely measure and manage landfill gas concentrations, ensuring optimal methane extraction and operational efficiency.

Highly accurate landfill gas monitoring and flow calculation in a portable, certified instrument.

Features

Certified to ATEX, IECEx, CSA, MCERTS and ISO17025 (UKAS calibration)
Measures percentages of methane (CH₄), carbon dioxide (CO₂), and oxygen (O₂)
Optional measurement of CO (hydrogen compensated), H₂S, NH₃, and H₂ with internal sensor
Simultaneous static and differential pressure recording
Custom user settings and an easy gas reading function
Calculates gas flow (m³/h) and calorific value (kW), with external hardware and software
Data logging and profiling capability for up to 6 gases
Modular and upgradeable design
Choice of additional gases and external GPS/field navigator
3 year warranty with robust, reliable construction
Easy-to-read high resolution 4.3” colour TFT display
Wireless Bluetooth, USB connectivity and memory for 2,000 IDs and 4,000 readings

Applications

Landfill gas field optimisation
Landfill gas energy calculation
Flare and engine output estimation

Benefits

Helps balancing of landfill gas fields for maximum methane output
Allows real-time adjustments for operational optimisation
No need for self-certification of external anemometer
Maximises revenue from methane extraction and power generation
Simple to use and read on site
