GMH 3830
Resistive material tester

The GMH 3830 offers decisive advantages in handling, usability, functionality and accuracy. The absolute moisture of 494 materials is displayed directly and can be automatically converted to the water content. The awkward use of conversion tables belongs to the past. For each humidity value displayed, you still get a humidity evaluation (wet / damp / dry) informing you of the status of the material being measured. Of course, the existing wood groups A, B, C and D of the previous model will continue to be supported.

Generic. applications:
Precision measurements of sawn timber, chipboard, veneers, sawdust, wood wool, flax, straw, hay, concrete, brick, screed, plaster, lime mortar, cement mortar, paper, cardboard, textiles, wood chips, etc.

Architects, appraisers, home builders, painters, carpenters, parquet layers, tilers, wood processing companies, technical wood drying, contractors, water damage restoration, textile industry, etc.
