This pocket-sized instrument measures the moisture levels in wood, paper, cardboard and building materials (mortar, concrete and plaster). It also measures ambient temperature.
In combination with the reading displayed on the backlit LCD screen, it has a panel of three colored LEDs (green, yellow and red) to provide a quick visual indication of the percentage of moisture in the object being tested. A data hold feature locks the reading on the screen. It also has a low battery indicator and powers off after 15 seconds of inactivity.
The unit measures 3 3/8" × 1 3/4" × 5/8" and weighs about 1 1/2 oz. It has a wrist strap and a snap-on cover to protect the probes, and runs on four included 1.5V button-cell batteries. Detailed instructions included.
