Hydromette BL Compact
4 Notes on Use
4.1
General Notes
Wood moisture measurement using the Hydromette BL Compact is
by means of resistance measurement. This allows direct display of
moisture content in percent by weight. The display range is
between 6% and 25% with a 4-stage wood type correction.
Measurement of building and material moisture is also by means of
resistance measurement. The display range is between 0.4% and
6.0% weight, depending on the respective material.

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. The more water present, the more conductive is
the wood and the lower the electrical resistance.
