For moisture checks below the surface, probe length is the decisive detail. This brush probe family gives users two clear options for material moisture measurement: GBSK 91 for depths up to approx. 100 mm and GBSL 91 for depths up to approx. 300 mm.
The short version supports shallower measurements, while the long version reaches further into the material. Both variants are shipped as a pair, making the family easy to identify and select for the required measuring depth.
GBSK 91 is the short brush probe version for material moisture measurement at depths up to approx. 100 mm.
GBSL 91 is the long brush probe version for material moisture measurement at depths up to approx. 300 mm.
The brush probes are supplied as a pair for the selected version.
