Ever wonder what a high quality moisture meter actually does?

Today, there are two variations of accurate moisture meter technology used to detect moisture penetration, wet pockets and mold development. I use a combination meter throughout each inspection.

Pin-type meters use wood, cellulose fibers and other hygroscopic materials as a circuit element, sending electrode currents through the material with two pins; this is based on the principle of electrical resistance, and identifies water presence within the material.

Pin-less meters perform the same function as models with pins, but use radio frequency signals in place of electrical currents. These meters emit signals into the scanned surface, and do not physically enter or damage the tested surface. Pin-less meters are ideal for scanning larger surface areas in a short timeframe, and serve best to highlight areas for further testing and inspection. Pin-type meters are better suited for exact and precise measurements, and can read moisture levels at various penetration points and locations within surfaces.

These meters, which measure moisture content (MC), accurately test surfaces and areas for moisture which may make the material being tested susceptible to fungal growth and spread. For example, in wood surfaces with MC readings above 20% mold spores can develop. Other materials, such as drywall, have different tolerances for MC before mold becomes a problem, check with a mold remediation expert for more information.

FLIR Spot Thermal Camera Used On Every Inspection

Equipped with FLIR's exclusive Lepton® micro thermal sensor, these cameras let you see the heat so you know exactly where to target the measurement spot. Easily find unseen hot and cold spots for instant troubleshooting. Thermal cameras make pictures out of temperature differences to show you hidden moisture intrusion signs, where heat loss is occurring, and electrical hot spots. With these cameras I can inspect for overheating caused by mechanical wear and tear, and scan to see what’s making it feel drafty.
