For this purpose the 1-, 10, resp. 60-min. measuring cycle (flow or diffusion) have
to
be chosen at the AlphaGUARD and the analog input 1 and 2 have to be adapted
to the used Multisensor Unit (see 7.2.8). Now the correctness of the appearing
measuring values can be displayed in the screen of Acquisition 2/5 (see 7.1.2).
Soil gas probe
The soil gas probe has been reliably applied for many years in conventional soil
gas analysis. It is suited for manual as well as for machine-driven propulsion
(adaptor for striking tools of the types Cobra, Bosch, Wacker and Makita). The
exchangeable drilling tip, the insertable capillary probe and the aqua-stop filter
ensure easy and safe sampling.
The AlphaGUARD as measuring and recording device provides optimized features
for soil gas measurement, e.g. short recovery time (typically: 5 min), even after
measuring extremely high radon concentrations.
A sampling method, developed in cooperation with GGD Leipzig is provided. This
approach is based on the experience with several thousand measurements. The
expenditure of time for one measurement point is approx. 15 min.
The soil gas probe can optionally be completed by an inflatable bag (packer) for
airtight measurements when using existing drill holes (ø 35–42 mm). Moreover, an
extension set up to 10 m as well as lifting tools or hydraulic extraction devices for
safely pulling out the rod are available on request.
