Ion Science GasClam 2 is a unique in-hole gas monitoring device that is approved for use in hazardous regions by ATEX Zone 1. Ensured by IECEx certification. Atmospheric, subterranean, and groundwater pressures and levels are all monitored by GasClam 2, which also measures unmanned continuous ground gas concentration data. This data reduces the amount of mystery surrounding what lies beneath the surface. It is possible to forecast future changes in the ground gas regime by tracking the current process of managing it.
pecuniary incentives can be found at several levels in GasClam 2. The first cost-cutting measure is a reduction in the number of field engineer visits. As regulatory data requirements are satisfied more quickly, the time of monitoring programs can be reduced. In order to save the most money, it is important to develop solutions that are appropriate rather than over-engineered.
