Wöhler HBF 420 Moisture Meter
APPLICATION
With its unique combination of electri-
cal resistance measuring technique and
dielectric measurement the Wöhler
HBF 420 wood and building materials
moisture meter represents an ideal
hand-held instrument to assess the
moisture content of materials in a wide
range of applications:
· Building diagnostics: Damage analy-
sis, leak detection
· Building work: Preparatory measure-
ments before applying paint, installing
floor coverings etc.
· Fuel management: Assessing wood
fuel materials
ADVANTAGES
· Ability to assess building and wood
moisture with one instrument
· Dielectric measuring technique, ideal
to quickly assess moisture and mea-
sure the moisture profiles of building
materials
· Resistance measurements to precisely
determine the moisture content of
wood:
· Automatic temperature compensation
after entering the material temperature
· Wood species correction via material
codes
· Calibration kit facilitates on-the-spot
measurement value verification
· Adjustable alarm threshold
