There is also a danger of injury due to careless handling of the measuring pins during the measuring procedure. Before pressing the electrode pins into walls or ceilings, ensure that no electrical cables, water pipes or other utilities are present using suitable means. Hydromette BL Compact...
Introduction 1 Introduction Description The Hydromette BL Compact is an electronic moisture meter for various types of wood and soft building and insulating materials with a 3-line LCD display. The measuring pins are pressed into the respective medium and allow recording of the moisture content of...

The knurled screws must be loosened to replace the electrodes. The pins can then be easily replaced. Care must be taken that the knurled screws are always sufficiently tightened to prevent measuring errors and the area between the pins is kept clean. Hydromette BL Compact...
Notes on Measuring Wood Moisture 4.2.1 Introduction The Hydromette BL Compact works by the well-known principle of electrical resistance or conductivity measurement. This method is based on the fact that electrical resistance is closely related to the respective wood moisture content. The conductivity of oven-dried wood is very low and the resistance so great that practically no current can flow.

6.0% to 7.5% wood moisture (corresponds to 30–40% rel. humidity and 20-25° C) and in the summer months approx. 10.5% to 13.0% (corresponds to 60–70% rel. humidity and 25° C). Additional data and tables can be found on the internet. Hydromette BL Compact...
In contrast, wood swells when it absorbs moisture from the surrounding air below the fibre saturation range. This is a very complex process. If you are interested in this topic we recommended searching for suitable information sources on the internet. Hydromette BL Compact...
Notes on Building Moisture Measurements 4.3.1 Introduction The Hydromette BL Compact works by the well-known principle of electrical resistance or conductivity measurement. This method is based on the fact that electrical resistance is closely related to the respective material moisture content. The conductivity of oven- dried material is very low and the resistance so great that practically no current can flow.
