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 roofing moisture meter detects and measures leaks within the roofing structure. Ideal for water leak detection in roofing materials and integrity testing.

Features:

• Complies to ASTM D7954
• Non-destructive impedance moisture meter.
• Three ranges of sensitivity enabling the inspection of a variety of roof membranes and insulation thicknesses.
• Ergonomic easy-reach and easy to operate control panel.
• Leak tracing, water leak detection, problem sourcing, and an instantaneous and clear indication of roof condition.
• Fast readings over large roof areas in a short time frame.
• Work in normal daylight hours.
• Faster and more user friendly than nuclear meters.
• Easy and safe to use with no regulatory restrictions or operating license required.
• Dependable solid state circuitry and rugged molded body for long-term reliability.
• Battery powered - 9 Volt PP3.
• Detect moisture in roofs without tearing them apart.

Range selection:

The Dec Scanner has an integrated and adjustable calibration ability allowing for precise comparative readings. There are 3 Ranges, and they should be selected as best suits the surface under test, for example:

Range 1 - Most suitable for single-ply and thin roof coverings such as PVC, Hypalon and other smooth surfaces where insulation is wet and moisture is close to the surface.

Range 2 - Most suitable for multi-ply built-up and modified systems, mineral surfaced felts, and other smooth or gravel surfaces where insulation is less wet and moisture is below the surface.

Range 3 - Most suitable for thicker roof coverings such as mastic asphalt, thick gravel and stone surfaced roofing.

Operating procedure:

Moisture detection testing can be done at the time of installation for warranty auditing and quality control, as part of an ongoing maintenance program, or prior to re-roofing or repair of damaged roofs. The Dec Scanner is a durable but lightweight instrument that is easily transported to the roof surface. Having determined a known acceptably dry area, one of three sensitivity ranges is selected, and the Dec Scanner is ready to use. Without causing any damage to the roof surface, the Dec Scanner is moved over the tested area. The Dec Scanner gives continuous moisture condition readings, from which a moisture map of the surface can be drawn up, and leaks traced to their source.
