Wood moisture meter especially suitable for wood fiber insulation materials

Product question?

The BL H 41 unit is a resitance-basedmeasuring device for determining the moisture of wood and, in particular, of wood fiber insulating materials.

In co-operation with well-known manufacturers, GANN developed characteristic curves for a wide range of insulating materials in order to display the moisture content directly (in weight %). These curves are grouped according to the gross denstity of the material (in kg/m³) and the board manufacturing process (wet/dry).
For example, the Hydromette can be used to check a facade prior to plastering in order to ensure that future moisture-induced damage is avoided (e.g. flaking of plastering or lignin exudation).

In addition, the BL H 41 enables precise measurements of sawn timber (up to 180 mm in thickness), chipboards, and veneers before and after processing.

The Hydromette meter is equipped with a wood temperature compensation, which automatically adjusts the measured value to the set temperature (of the respective object).

This device is especially suited for everyone who processes or assesses wood fibre insulating materials, but also for joiner's workshops, parquet recliners and painting contractors.
