Detailed Description for Moisture Meters

A moisture meter is used to measure the percentage of water in a given substance. This content can be used to determine if the material is ready to use, unexpectedly wet or dry, or otherwise in need of prolonged inspection.


Wood and paper product is very sensitive to their moisture content. Physical property is strongly affected by moisture content. Dimensioning also changes with moisture content.






Check for moisture content in wood, paper, cardboard and building materials such as sheetrock, concrete, mortar, plaster.


LCD display provides a moisture or a temperature measurement


Three color LED provide a very quick moisture indication:


Backlight for operation in light-less areas


resolution: Wood  0.1%, Building Materia 0.01%


Green - “air-dry conditions, Yellow - increased moisture, Red - excess moisture


Settable measuring ranges for different materials. HOLD Function.


Auto-Power-Off function. Back Light Function.


Protective cover for safe storage.


Attached by carrying strap.


Battery Low indication






why-cut logs can have a moisture content (MC) of an  80% or more, depends on species. Since wood shrinks, and can split, twist or otherwise change structure as it dries, most wood is dried before being used. This is most often done using a kiln, but may use the air drying method, which is rather slow. In most parts of the United States, the minimum moisture content that can be generally obtained by air drying is about 12 to 15 percent. Most air-dried material is usually closer to 20 percent humidity content when used.[1]


In-kiln drying is usually monitored by some type of moisture meter. Moisture meters are used to calculate the amount of water in the wood so that the woodworker can determine if it is suitable for the desired purpose. Building inspectors and much more, carpenters, hobbyists, and other woodworkers essentially are required to have moisture meters. Wood flooring installers, for example, have to verify that the MC of the wood matches the relative moisture content in the air of the building. If this step is skipped, a vast array of problems may present itself: cracking, cupping, crowning, buckling, sunken joints, and cracked finishes.


The problems caused by varying degrees of moisture amount in wood go beyond simple shrinkage in the dimensions of wood parts. Problems with distortions in the structure of the wood, such as twisting, warping, and cupping, occur because of the difference in the degree of dimensional alteration in wood cells tangentially (perpendicular to the grain and parallel to the growth rings) versus radially (perpendicular to the growth rings). 


The amount of overall shrinkage lumber will undergo in the drying process varies from wood species to wood species. The difference between radial and tangential shrinkage also varies from species to species. Woods with a low ratio of tangential to radial shrinkages, such as teak and mahogany, are less prone to distortion due to changes in moisture content than woods with a high ratio, such as eastern white pine and certain species of oak. Species with both low overall shrinkage and a low tangential/radial shrinkage ratio are more stable and will react better to changes in moisture content.[3]


For wood that is to be used in making furniture, for wood floors, in construction or for any building project, the ideal state is one of equilibrium moisture content (EMC). EMC means that the wood is in balance with the relative humidity it surrounding environment, and is therefore neither gaining or losing in moisture content. In reality, however, it is extremely rare for an environment to maintain a constant fixed relative humidity, and some degree of dimensional change along with seasonal changes in relative humidity is to be expected.


A moisture meter gives a reading of the approximate moisture content of wood. The reading helps in determining whether the wood is suitably dry for its intended purpose. The moisture content reading can also assist in planning a project design that will accommodate future changes in dimension caused by changes in relative humidity.


For typical woodworking operations, two basic types of moisture meter are available.One type measures the electrical resistance of the wood fibers, which becomes increasingly lower as the moisture content of the wood rises. With the electrical resistance type of moisture meter, two electrodes are driven into the wood fibers and the electrical resistance is translated into moisture content on the device’s electronic or dial output. The second type of moisture meter relies on the dielectric properties of wood and requires only surface contact with the wood.
