    GMH 3831, Precision Material and Building Moisture Meter, without Accessories

    For the measurement of moisture in wood, building materials, insulating materials, straw, hay, paper, textiles and more...
    The GMH3831 offers important advantages in handling, user-friendliness, functional range and accuracy for your metrological work. The absolute moisture content of 494 materials is displayed directly. The cumbersome usage of calculation tables now is history. Additionally you get a evaluation of your material state (wet/dry) of nearly all materials instantly.

    • 466 wood characteristic curves
    • 28 building material characteristic curves
    • moisture evaluation
    • display of moisture content -"u" or wet-basis moisture content "w"
    • external temperature probes connectable
    • serial interface or analog output 0-1V, freely adjustable
    • Future-proof via updates

      General applications:
      Precision measurements in cut wood, chip board, veneer, sawdust, wood chips, wood wool, flax, straw, hay, concrete, gas concrete, bricks, wash floor, cast, limestone mortar, cement mortar, paper, carton, textiles etc.

      Users:
      Architects, experts, inspectors, building contractors, painters, carpenters, parquet joiners, floor tilers,
      wood works, timber desiccation plants, building repair companies, textile industries etc.

      The instrument is supplied without external probes. It has a BNC socket for the moisture probes and a thermovoltage-free socket for external thermocouples of the type K.
      Suitable sensor can be ordered additionally according to the following presentation.
      There is also the possibility to order complete accessory Sets for wood moisture or for wood and building moisture.
      For the measurement of hard materials, there are optional accessories available.
