Description
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
