Soil Probe XRS 8612

This probe is a special development for leak detection at subterranean tanks or lines and used along with the XRS 9012.

Soil Probe XRS 8612 In order to prevent the immediate dissipation of the hydrogen upon reaching the surface due to its high volatility, the probe absorbs the gas directly from the ground or flooring. Hence it is possible to precisely locate even the smallest of leaks in tubes or containers without the need to lay these bare by means of drilling or excavating.

Part of the equipment of the soil probe XRS 8612 is a vacuum pump with two operating speeds. The used hydrogen sensor is identical in construction to the sensor of the XRS 9012. The integration of this sensor results in the fact that the traced gas is reported faster than would be possible with the gas fed to the leak detector via a hose.

The reliable battery of the XRS 9012 is also used for the soil probe XRS 8612. A light-emitting diode indicates, when the battery needs to be charged. The battery can be charged indefinitely often and without time limit.

In order to prevent, that water is sucked into the probe, the soil probe XRS 8612 is provided with dust filter and overflow valve. An LED indicates, when the overflow valve is closed. Simply via the push of a button the valve can be set back to operating state.
