Multifunction Moisture Meters

 Extech’s advanced moisture meters offer much more than moisture readings:
Non-invasive, pin-less technology protects work surfaces. Environmental readings (RH, air and surface
temperatures, dew point, GPP, vapor pressure, condensation levels) add extensive insight without extra meters. Remote specialty probes expand versatility. And available MeterLink™ technology transmits readings wirelessly to a FLIR infrared camera for accelerated diagnostics.

Moisture Meter FAQ's

Does my moisture meter read moisture content or does it give me a relative reading?

It is meter dependent. Some of our moisture meters directly read % wood moisture and others provide a relative scale. Check the data sheet for the meter of interest.



Do you have moisture meters that will work on brick, concrete & other construction materials?

Yes, The MO257 can be used to measure moisture in brick, concrete and other building materials. Note that the MO257 measures moisture from a .75" to 1.5" depth in the material being measured.


For making wood measurements with the pin style moisture meters – how far do the pins on my meter need to be inserted for an accurate measurement?

Insertion into the wood should be to at least a 0.08” (2mm) depth for the highest accuracy. If this is not possible, carefully insert the test pins as far as possible without undue force.
