GasClam 2 continuous ground gas monitor 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 applications include:
- Soil contamination and Remediation
- Decontamination
- Emergency Response
- Exploration
Features
Using GasClam 2 continuous ground gas detector provides a hierarchy of financial benefits, these include:
- Reduced number of site visits by a field engineer
- Reducing the overall length of monitoring programmes as legislative data requirements can be met quicker
- The third, and largest savings is made by designing appropriate, rather than over-engineered, solutions based on complete and robust data
