The Tramex Dec Scanner is a mobile non-destructive impedance scanner designed for the instant surveying of moisture conditions in flat roofing and waterproofing systems per ASTM D7954. The Dec Scanner roof moisture meter detects and measures leaks within the roofing structure. Featuring three ranges of sensitivity and with a maximum depth penetration of 6" (152cm), the Dec Scanner enables the inspection of a variety of roof membranes and insulation thicknesses. Readings are instant and a flat roof area of up to 100,000 square feet can be reasonably covered in a day. As it is easy and safe to use with no regulatory restrictions or operating license required, the Dec Scanner is ideal for water leak detection and integrity testing in roofing materials.
