Tramex DS2 Offers

Detects and evaluates moisture conditions in roofing and waterproofing systems, this non-destructive scanner features three ranges of sensitivity to enable the surveying of a variety of roof types and roofing depths. Additionally, it can detect moisture in most roofing and waterproofing systems.

Features

• Non-destructive impedance moisture scanner
• 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, problem sourcing and an instantaneous and clear indication of roof condition
• Fast and precise 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 - 2 x 9 Volt PP3
• Complies to ASTM D7954
• Detect moisture in roofs without tearing them apart

Design

Detects and evaluates the moisture conditions within roofing systems by non-destructively measuring the electrical impedance. A low frequency electronic signal is generated, transmitted into the material under test via one of the two electrodes incorporated in the rubber electrode mat, and received by the second electrode. The strength of this signal varies in proportion to the amount of moisture in the material under test. This scanner determines the strength of the current and converts this to a comparative moisture content value. By moving this scanner across a roof surface in a regular pattern, a continuous reading is obtained, and areas that contain moisture can be readily identified.

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. This 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 it is ready to use. Without causing any damage to the roof surface, this scanner is moved over the tested area. It gives continuous moisture condition readings, from which a moisture map of the surface can be drawn up, and leaks traced to their source.

Range selection

This scanner has an integrated and adjustable calibration ability allowing for precise comparative readings. There are three 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

Applications

• Roofing
• Waterproofing systems
