How to use Protimeter Aquant2
Measure moisture correctly and understand the readings

The Protimeter Aquant2 has been designed for measuring moisture in buildings utilising a sub-surface search mode. With its ergonomic design, digital display and easy-of-use, this instrument has become the recommended moisture detection tool for building professionals.

Protimeter Aquant2 Sub-Surface Search Mode
The biggest problem with taking moisture readings, is finding the affected areas, even if the surface has a covering. The search mode provides a non-invasive technique for scanning walls and floors for moisture without damaging the surface.

When held against the surface, as shown, the instrument transmits a signal into the material. The search mode determines the moisture content from the returned signal strength.

The relative moisture level is shown on the digital display and its moisture condition is shown on the accompanying scale of colorcoded lights.

The nominal depth of the measurement is 19 mm dependent on the density and other characteristics of the material.

This measurement presentation helps the user to:
• Search for moisture behind wall and floor coverings (tile and vinyl)
• Assess, if the material is in a dry, borderline or damp condition
• Map the extent of the problem numerically
• Finds moisture at depth where moisture is not always directly visible
• 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.

Determining the readings
The Protimeter Aquant2 features a digital LCD display supported by the Protimeters revolutionary colour display which is a collection of 60 LEDs divided into color-coded zones signify moisture readings of the material under investigation. The green, yellow, and red color-coded zones indicate the following:

Search Mode Readings
The Protimeter Aquant2 features a digital LCD display, detailing the moisture readings from 0 to 999 REL (relative content). The REL value is the theoretical moisture level that indicates the potential severity of the moisture content within the material being tested. The higher the reading, the higher the moisture content. Any reading which displays an LED in the red zone, is too damp. The WME value is the theoretical moisture level that would be attained by wood that is in moisture equilibrium with the material being tested.

Supporting the digital LCD display, a colour LEDs will light up to allow the surveyor to quickly determine the moisture level. The LEDs are subdivided into three colour zones, green, yellow, and red indicating the severity of the moisture reading. In most cases it is quicker and easier to determine the reading using the colour.
• In the green zone, moisture levels are in a safe air-dry condition
• In the yellow zone, moisture levels are higher than normal but not critical; further investigation is recommended
• In the red zone, moisture levels are excessive and too high. If sustained, high moisture levels will lead to decay
