Which type of moisture meter works best for EIFS?
To quickly identify wet areas, a pinless meter is easy to use. Pinless meters offer the convenience of testing a large area quickly, and help you determine if further testing is required in certain spots. Pinless meters read moisture closest to the source of the magnetic field, in this case, at the surface. Most pin-less meters read at a depth from 1/2″ to 1″. Moisture that resides in the substrate or insulation may go undetected without using a deep penetrating electrode. It is also important to remember that any metal or other conductive material behind the EIFS may give false readings. A pin type meter, on the other hand, is the best way to identify the exact location of moisture in the substrate and framing. A pin-type uses two pins that penetrate into the building at the users desired depth. When insulated contact pins are used, only the uncoated tips are exposed to the wood fiber, providing an accurate reading of moisture content at various levels of penetration. Pin-type meters
