IN-SITU CONTINUOUS GROUND GAS MONITOR
Applications
Key applications for the ground gas monitor include:
  • Hydro-fracking
  • Vapour Intrusion
  • Landfill gas monitoring for long term profiling
  • Brownfield for development issues
  • Below ground carbon capture
  • CO2 sequestration
  • Monitoring for coal mine fires
  • Leakage in crude/petroleum
  • Solvent storage and filling stations
  • Refineries for local compliance
  • Storage monitoring regimes
Description
Monitor CH4, O2, O2, CO2, CO, H2S and VOCs continuously, for up to 3 months!

Ground Gas Monitor is the first to give continuous, unmanned data collection. Ideal for landfill gas monitoring applications, the Ground Gas Monitor logs long-term, real trend information. A revolution in gas management and risk prediction, informed decisions can now be made on accurate, reliable data. 

The ground gas monitor measures methane, carbon dioxide and oxygen concentrations as well as atmospheric pressure and temperature. Optional CO, H2S and VOC, plus water depth are available along with a telemetry module for remote, real time data communication.

The ground gas monitor’s sampling frequency can be set and is variable from two minutes, to once daily. Data is downloaded to a PC or viewed remotely using the optional GPRS telemetry system.

Manufactured from stainless steel, the Ground Gas Monitor is Intrinsically Safe, environmentally sealed and ingress protection rated IP-68. Battery operated; Ground Gas Monitor can be powered for up to 1 month based on hourly sampling.
