Ground Gas Detector

GasClam 2

Continuous Ground Gas Detector

The GasClam 2 is perfect for continuous ground gas monitoring as it collects unmanned continuous ground gas concentration data as well as parameters that are known to control it – subsurface pressure, atmospheric pressure and water level.

Typical ground gas monitoring applications of the GasClam 2 include:

  • Soil contamination and Remediation
  • Decontamination
  • Emergency Response
  • Exploration

GasClam 2 – Features

Using the GasClam 2 for monitoring ground gas provides a hierarchy of financial benefits, these include:

  • Reduced number of site visits by a field engineer
  • Reducing the overall length of ground gas monitoring programmes as legislative data requirements can be met quicker
  • The third, and largest savings are made by designing appropriate, rather than over-engineered, solutions based on complete and robust data

Ultimate Performance

  • Supports and industry recognised best practice approach to ground-gas monitoring
  • Battery powered deployment for over 3 months (depending on logging frequency)
  • Reduces number of site visits

Ultimate Safety

  • Demonstrates regulatory compliance and due diligence
  • Optimised site management with insights from continuous ground gas monitoring

Ultimate Flexibility

  • GasClam2 ground gas monitor fits in to standard 50mm/2” borehole
  • Discrete installation
