Building Inspection


Before & During Construction

Construction lumber for various types of buildings is generally best suited at moisture contents around 12% to 15%. If you are purchasing or accepting deliveries of lumber, a moisture meter is extremely useful in verifying this! Some building codes actually set limits on the allowed moisture content. For example, most codes in Canada require a maximum moisture content of 19%. For this kind of application, a pin-type meter is usually the best buy. The pinholes made by the meter will not be visible when construction is complete. The Model CMT-908 is very popular with construction companies because of the large clear digital readout and wide range (4% to 80%) and ability to measure with both pin-type and pinless modes.

After Construction

A common need is to inspect drywall, plaster, roofing, insulation, or flooring in a finished and lived-in building, in order to search for possible water leaks. Here the Model CT100 pinless meter is the perfect choice. With no physical damage and one-inch depth sensing, this meter can reveal potential problem areas long before there is any visible sign of water. The Model CT808 is frequently used by air quality control companies to inspect drywall (a toxic fungus can grow behind the drywall if the moisture level is too high). We also have a pinless meter which can sense to a depth of 1.5 inches, with an external sensing pad connected to the meter by a cable, so you can reach into otherwise inaccessible places (GRP200 & GRP200S).
