    What is the difference between Relative and WME (wood moisture equivalent) readings?

    Relative readings are comparative readings used for determining the moisture content level from one area to another of the same material. Ideally you would take a reading from an area you know to be d...

    Can my moisture meter be used on ceramics or fiberglass?

    Our moisture meters are not calibrated for ceramics or fiberglass in terms of WME readings. However, our pinless moisture meters could give relative readings on these materials..

    Are there any pinless meters which measure WME (wood moisture equivalence)?

    All of the pinless sensors on our moisture meters provide REL (relative) readings only.

    Are there any moisture meters which have a NIST Certification?

    We currently do not offer any type of certification for our moisture meters. They would need to be sent to a certification lab for that.

    On my pinless moisture meter, what materials can be measured with each measurement mode (Wall, Masonry, Hardwood, Softwood)?

    Choosing the Hardwood or Softwood mode depends solely on the species of wood. For example, oak is a hardwood and pine is a softwood. Keep in mind that manufactured "woods" (such as plywood, pressed wo...
