BM31 Moisture Meter

The BM31 is an electronic Moisture Meter, by which moisture near to surface of different materials can be detected fast, easy,and time saving. Moisture distribution can be located at walls, floors or ceilings.

Due to the dielectric measurement method the moisture indication happens non-destructive, no electrodes or probes need to be put into the messured object.The BM31 is not only ready to use immidiately, it convinces about a short response time during measurement and shows the user, besides the current real time measured value, helpful additional informations like minimal and maximum values at a push of a button on the readable backlit display. Furthermore the current measured value can be recorded by hold function.

With this Moisture measurement instrument it ist not only possible to indicate fast various material moisture values near surface, it is perfectly suitable for preliminary test of the workability of building material at cm measurement.

Benefits in practice:

  • Trotec: 100 % development, design, manufacturing
  • Fast and non-destructive indication of moisture distributions in near-surface regions
  • Useful preliminary test for CM measurements
  • Minimum value, maximum value and hold function
  • Automatic function and battery test
