The James T-M-170 Moisture Master™
A Hand Held
Instrument for Fast Accurate Measurement of Moisture Content in Solid
Materials.
Locate leaking pipes in walls and floors. Locate seeping water in basements &
masonry tanks. Check moisture level of material before
applying coatings or adhesives. Curing condition of wood, stucco, and
other construction materials.
Direct read out of moisture content, no
charts or tables required. Separate modes for concrete, brick,
different woods, and gypsum. Measures moisture in most solid
materials. Color coded LED indicates moisture
condition of material Alarm values can be set by user. Pin mode for low density materials,
capacitive mode for high density materials.
The James
Instruments Moisture Master™ utilizes the latest electronic technology to
measure the quantity of water within its sensing field. The unit has
two modes of operation the pin mode, and search mode. In the pin mode,
two pins are pushed into the material and a high frequency field is
created between these two pins. In the search mode the unit uses a high
frequency capacitive sensor to sample a large volume of the material,
instantaneously. Changes in this electromagnetic field are directly
proportional to the dielectric constant of the material through which it
passes. As the dielectric constant of water is almost two orders of
magnitude greater than most non-metallic materials, variations in this
parameter can be correlated to the moisture content. After extensive
testing of various materials, relationships between the change in this
field and moisture content have been determined. These relationships
have been digitized and implemented using the latest in micro-computer
technology, thereby allowing the user the direct readout of moisture
content for concrete, masonry, hard wood, soft wood, gypsum, and brick.
The pin method has been found to be most effective in low density
materials such as fir wood or pine
wood. The search mode has been found to be most effective for higher
density materials such as brick, masonry, gypsum and
concrete.
