Ground Gas Monitors

Shawcity supply a wide range of Landfill and Ground Gas Monitoring instrumentation, such as the NEW Gasclam in-situ Borehole monitor which collects data in former landfill and brownfield sites allowing you to monitor effective site gas release activity as well as the GFM series of portable spot monitoring devices. 

Monitoring Landfill Gas
Monitoring of landfill gas frequently involves long journeys to remote locations. It is always time consuming and frequently challenging to get the information that is needed. But even after you have the data you need, is that good enough?
Site conditions never remain the same. Changes in weather conditions, atmospheric pressure and water table movement mean that if you want accurate and reliable data you must measure routinely. 
Hourly site visits are of course not practical. But hourly monitoring is now achievable with GasClam. Data storage in GasClam means you can collect data hourly and leave it unattended for 3 months before a return site visit is needed.
 
What is a borehole?

 

A borehole is a term for describing a shaft that is drilled into the ground.

the New Gasclam Monitor sits inside a borehole and monitors gas escaping from the ground.
