Measures the moisture content of wood

and construction material with a smoothsurface, by holding the instrument onthe material for about half a second.

Density setting for wood rangingbetween 250 and 1100 kg/m3 foraccurate measurement.

Measures through paint layers or plasticfilm wrap.

Ideal for quick checks and final

inspections.
