    I work for a Floor Covering company. We mainly use unfinished 3/4 thick wood and engineering pre-finished. I am the quality control rep. I need your advise for a moisture meter, humidity meter and any other meter that could help me to make my job more accurate and helpful in my everyday duty.

      Your best bet is to arm yourself with an MMC220 wood moisture meter, TH200 thermohygrometer for documenting the RH% and temperature in the air, and our WOODH2O smart phone app available for FREE. Using the information from the TH200, you input it into the WOODH2O app to calculate equilibrium moisture content. Using the MMC220, you get the actual finished flooring/subfloor MC%, and compare it to the EMC. This allows you to know if the product/products have acclimated to the environment. Should there ever be a problem with the floor after installation, having all of this information in the job file may also make it easier to diagnose the problem.

    what about shell mc verses core mc? emc is reached when shell mc and core mc are the same. how does your equipment measure shell verses core? We currently use a Delmhorst pin meter to do this on aromatic cedar up to 10/4 thick. How does youe equipment do this?

    • Jason Spangler says:

      All of our products don’t distinguish between shell and core. Wagner meters measure past the surface as far as an inch into the material. So, in essence, the reading provided is an average moisture content under the meters up to an inch penetration.

      • Lou LaCourse says:

        When we dry wood it is essential there isn’t a large difference between the core and shell as the shell provides a conduit for moisture from the core to be released and a large difference can break the conduit and our drying process comes to a stop until we wet the shell enough to begin drying again. How does you system compensate for this?

        • Jason Spangler says:

          I think it’d be best if you could give us a call so we can discuss this further. You can reach us at 1-800-634-9961, Monday through Friday between 7:30 am and 4:00 pm PT.
