Protimeter Surveymaster 3 BLD5375

Search Mode – Non-Invasive

The search mode is used to assess the moisture level beneath the surface of solid walls and floors independently of surface conditions. The nominal depth of the measurement is 3/4 inch (19 mm); this depends on the density and other characteristics of the material being measured. When held against the surface, as shown below, the instrument transmits a signal into the material. The relative moisture level is shown on the digital display and its moisture condition is shown on the accompanying scale of colour-coded lights. This measurement presentation helps the user to:

• Look for moisture behind wall and floor coverings, such as tile and vinyl
• Assess, in relative terms, if the material is in a dry, borderline or damp condition
• Map the extent of the problem numerically
• Non-invasive pinless radio frequency finds moisture at depth where moisture is not always directly visible – up to 3/4 in (25.4 mm) below the surface
• This mode of measurement is not adversely affected by the presence of surface moisture

Applications: Shower pans, behind ceramic tile, fine finishes, water stains, tile and vinyl floor coverings, joists, around toilets, drywall, below grade floors and walls, plaster, masonry, concrete and concrete block. Note: Metal additives in concrete can create false positive readings.

Measure Mode – Pin-Type

This mode is used to measure the moisture level at the surface and at incremental depth, when used with the auxiliary probes. Measure mode readings are precise and specific to the immediate area of contact of the electrodes. The actual moisture content of wood is shown on the digital display with the corresponding moisture condition shown on the accompanying scale of colour-coded lights. Wood Moisture Equivalent (WME) values are shown for other non-conductive, porous building materials.

• Pin-type probes measure moisture in wood and other building materials (use provided wood species calibration chart for more precise readings)
• Deep wall probes establish the presence of moisture in wall cavity insulation, sub and surface structures

Options

• Exterior Insulation and Finished Systems (EIFS) probe finds moisture in exterior insulation finishing systems
• Hammer electrode for wood floor applications

Applications: Wood and wood floors, subfloors, drywall, concrete and concrete block, stucco, plaster, masonry and EIFS

Reference mode (Patent Pending)

In both Pin and Search mode, GE’s patent pending Reference Mode can be used. Reference mode can be useful when trying to establish what materials are above or below a point of reference or dry standard.

Measure the dry standard or baseline material until the meter’s reading is stable then press for seconds. This will store the reading until the mode changes of the meter turns off. Now all readings taken after will be displayed as normal, but below you will see a second reading that shows you if the material is measured above or below the original reading.
