• Wood moisture content in excess of 18% - 20%
may provide an environment for termite and
wood-boring insects to thrive and multiply. Wood
at these high levels can also support mold and
biological growth.
• Wood at 28% moisture content is considered to
have reached fiber saturation point.
g. Avoid taking readings on wood from the top of a
stack stored outside as these may be affected by
surface moisture from recent rain.
h. When taking readings in chemically treated
wood, it is advisable to allow for possible effects
that the treatment may have on readings.
Depth of field penetration
Depending on the density of the material being
tested, the instrument field can penetrate
approximately 30mm (1¼ inches) below the
surface. When testing thin materials such as
wood veneers it is recommended that they are
stacked to at least that thickness.
