For nearly 85 years General Tools has grown to become the recognized industry leader for specialty hand tools and instruments. The MMD900 is designed for use in woodworking, water damage restoration, building construction and home renovation. The meter senses the moisture level of a material using either of two techniques: 1. inferring the material’s electrical conductivity from the current flow induced between a pair of steel pins placed on or into the material. The wetter a material, the higher its conductivity. The MMD900 is equipped with two pairs of test pin one pair on the top of the instrument and the other at the end of a cable and remote probe that can fit in tighter spaces. 2. Measuring the change in the material’s capacitance produced by the slight spreading of a local electric field generated by the meter. When the meter is powered on, two plates inside the back of the MMD900’s housing are charged with opposite polarity and pulsed at a high frequency. This causes current to flow, creating a three-dimensional electromagnetic wave at radio frequency that extends about 2 in. (50mm) perpendicular to the meter. When the back of the meter is placed against a wet material, the increased capacitance of the material distorts the wave’s electric field to an extent that can be measured. The distortion called the fringing field effect is proportional to the material’s moisture level.
