How a Pinless Moisture Meter Measures Moisture
A pinless meter is a “relative” or unit-less measurement device.
Unlike the PIN type moisture meter that measures %WME or electrical resistance, the Pinless meter
measures an electrical property of the material called relative permittivity. A pinless meter uses an
Electromagnetic signal to check the permittivity of a material.
The proper way to use a pinless meter is to make a measurement of a material of a known dryness.
Then make a measurement of an item of the same material, thickness, and construction of unknown
moisture content. Any rise in reading indicates moisture, or the presence of some other conductor or
high permittivity material (a metal stud behind the wall would produce higher readings).
Making multiple measurements over the suspected area is recommended to get an average reading of
the material. Practice and experience will help you to get a feel for the moisture content in that
material.
