Thank you for selecting the MEP - Moisture
Encounter Plus from Tramex.
The Moisture Encounter Plus is a patented
instrument, which enables non-invasive moisture
measurement and detection in a wide range of
building materials. The instrument operates on the
principle that the electrical impedance of a material
varies in proportion to its moisture content.
To measure/detect moisture, the two co-planar
conductive rubber electrodes mounted on the base
of the instrument case are lightly pressed onto the
wood or material sample. The instrument measures
the electrical impedance of the sample by creating a
low frequency alternating electric field between the
electrodes. This field penetrates the material under
test to a depth of approximately 30 mm (1¼ inches).
The very small alternating current flowing through
the field is inversely proportional to the impedance
of the material. The instrument detects this current,
determines its amplitude and, after processing,
drives the pointer of the moving coil meter to the
computed moisture value.
