Soil Sensor XRS 8212

For leak detection under the most difficult conditions

The soil sensor is employed for leak detection on soft ground, such as farmland, clay, sand, gravel, snow or marsh, and wherever the vegetation prevents the surface measuring head XRS 8612 from being used.

A few practical benefits:

  • Detects hydrogen in dry and wet ground, can be used in all types of soft ground
  • Hydrogen sensor integrated in the tip
  • Works without pump
  • Waterproof

The soil sensor XRS 8212 is used in combination with leak detector XRS 9012 and especially suited for leak detection under the most difficult of surrounding conditions.

Up to a certain magnitude hydrogen is soluble in water. Thus, the soil sensor XRS 8212 is also used in water to detect the dissolved hydrogen there.
