GMH 3810, Resistive Material Moisture Meter

with integrated measuring pins for measuring wood, plaster and building moisture.
New development with state-of-the-art microprocessor technique. 

The absolute weight moisture of 493 materials like i.e. concrete, floor finish, brick stones, gypsum, lime stones, cardboard, polystyrene, MDF, cement mortar, bitumen, etc. is directly indicated.

The inconvenient use of conversion tables is a thing of the past.

In addition to the indicated moisture reading you get a moisture evaluation (wet, moist, dry) in nine steps.

Due to the measuring needles, integrated in the fortified front plate, a multiplicity of measurements are possible without additional accessories. For measuring hard materials, we recommend the additional accessories.

Measuring principle:
moisture: resistive material-moisture-measuring,
matching DIN EN 13183-2:2002
