GasClam 2

Continuous soil / ground gas monitoring

 Gasclam background

 

GasClam 2

Key Features:

  • Continuous gas (methane, carbon dioxide, oxygen, hydrogen sulphide and VOC) monitoring with configurable logging intervals
  • Continuous atmospheric/borehole pressure and monitoring with configurable logging intervals
  • Battery powered deployment for over 3 months (depending on logging frequency)
  • External power option for extended deployment
  • Intrinsically safe for use in explosive atmospheres
  • Discrete installation
Using spot measurements to understand ground-gas regimes often results in high levels of uncertainty. Uncertainty exists as concentration changes over time and spot sampling only provides a snap shot of the ground gas regime at that instant. Considerable published material from experts who measure ground-gas and perform risk assessments question whether traditional methods of collecting data are adequate. This led Salamander to provide the definitive solution, the patented GasClam® 2, collects unmanned continuous ground gas concentration data as well as parameters that are known to control it – subsurface pressure, atmospheric pressure and water level. This information reduces uncertainty by providing the full picture of what is happening below ground, also by observing the process controlling the ground gas regime you can predict how it will change in the future. Using GasClam 2 therefore, provides a hierarchy of financial benefits, the first saving comes from reducing the number of site visits by a field engineer, the second saving comes from reducing the overall length of monitoring programmes as legislative data requirements can be met quicker and the third and largest saving is made by designing appropriate, rather than over-engineered, solutions based on complete and robust data.

Standard kits include: 

  • GasClam 2 continuous gas monitor
  • Rechargeable NiMh battery pack and charger
  • PC link cable
