Moisture Test Meters

What are they used for and who uses them?

Sonin Moisture Test Meters are used to detect moisture percentages in wood and other building materials. Moisture test meters are used in a variety of industries and are an invaluable tool for  home inspectors, woodworkers, furniture makers, contractors, roofers, do-it-yourselfers, painters and homeowners to name a few.

Sonin Moisture Test Meters are used to locate water leaks and check for wet rot as well as detecting levels of moisture that may be present in drywall, plaster, carpet and more that when left undetected could lead to the formation of dangerous mold that may go unnoticed causing hazardous conditions in the home or workplace. Moisture conditions will vary between regions of the country whereby conditions for moisture are greater along coastal areas and the Southern U.S. and of course will be dryer in desert climates.

Sonin Moisture Test Meters are necessary to check surfaces before painting, wallpapering or staining. Applying paint or stain on moist surfaces could lead to the product failing and possibly causing damage to the surface of the wall or decking material. Flooring and tile installers will want to use them to see if the surface will accept adhesive and carpet cleaners and restorers will use them to ensure proper dryness.

Sonin Moisture Meters should always be used to test the moisture content in firewood before burning in woodstoves or fireplaces in order to avoid your wood from smoking which can be dangerous. The Environmental Protection Agency recommends that sellers of wood stoves and forced air furnaces provide a moisture test meter so that only well-seasoned firewood is selected. Generally you want to see a reading of about 20% or less moisture content when selecting suitable firewood. Well-seasoned firewood will also burn more efficiently and not be wasted fuel.

Sonin makes several “pin type” Moisture Test Meters that can detect moisture in ranges of between 2-70% depending on the unit. These meters work by passing a current between the first pin and the second pin. The strength of the current indicates the amount of moisture in the material, as moisture acts as a conductor. Essentially, these meters measure the electrical resistance of the material which is then translated into moisture content on the devices analog or digital scale.

Models and uses.

Sonin makes both analog and digital models and a unit that uses a simple series of LED lights to output the reading.
