The Hydromette BL Compact B2 is a multi material non invasive moisture meter which uses the dielectric constant measuring /high-frequency principle.

With 7 different concrete/screed/plaster profiles stored in the meter, the BL Compact B2 is well suited to not only conventional locating of moisture in homes and building materials, it is also well specified for the measurement of moisture content by weight, in concrete,screed and plaster materials.

With a fast measuring determination and self calibration, simply turn on the BL Compact B2, hold against the wall or concrete and the unit will scan (using the capacitance method), up to 40 - 60mm from the surface.

The BL Compact B2 has an audible alarm, which will sound if the values exceed the set alarm limit.
Limits for the building materials can be set individually and the user guide sets out some key moisture parameters for the materials based on specific weight and environmental conditions.
