Soil Gas Probe [CN-SOIL]

When measuring radon underground, it is essential to collect samples without exposing them to the outside air. We offer a heavy-duty soil probe for this purpose.

 

Probe Placement and Connection

Soil Gas Probes operate anywhere above the water table, preferably in soil containing few stones. A pilot rod is hammered most of the way to the depth required, then removed and replaced with the drive rod inside the probe. Once it has been hammered down to the required depth, the drive rod is removed, creating a channel through which soil gas may flow upward.

The soil probe may be connected to the RAD7 by either pushing the plug-in hose connector into the probe. Tamping down the soil around the probe prevents the leakage of fresh air into the sample acquisition path or down the outside of the probe to the sampling point.

The Soil Gas Probe may be used in conjunction with the laboratory drying unit and the DRYSTIK, using the supplied plastic tubing.
