Moisture Meter for Materials and Wood
If you want to measure moisture quickly and, above all, in a way that does not damage the material, or monitor the drying process in materials such as wood or mineral building materials, the Trotec BM40 moisture meter is a reliable tool for the job. To do so, simply place the device’s measuring electrodes on the material being tested.
Moisture measurement is performed in a completely non-destructive manner using capacitance sensors and the dielectric measurement method, since no electrodes or probes need to be inserted into the material being measured. Correction factors are available for different types of materials to increase the accuracy of the measured values, which are given directly as mass percentages.
The ready-to-use BM40 impresses with its ease of use and fast response time during measurements.
Ambient temperature measurement, a battery status indicator, and an energy-saving automatic shut-off feature round out the versatile range of functions.
Advantages of a wood moisture meter:
- Development, design, manufacturing: 100% Trotec
- Rapid, Non-Destructive Moisture Measurement in Mineral Building Materials and Wood
- 10 adjustable material curves for the most common building materials and wood species
- Including measurement of the ambient air temperature
- Simple one-button control
- Direct display of the measured value as a percentage
- Battery Status Indicator
- Automatic Shutdown
- German industrial design optimized for practical use – registered design
