The Protimeter BLD5765 Aquant Moisture Meter (part number BLD5770) is a non-invasive moisture meter used to locate moisture quickly across a wide range of building materials. It is the sister product to the Surveymaster and is suited to surveying, cleaning or restoring a property after water damage, where finding where moisture sits, and how deep, decides whether a structure is safe to recover or to dry out further.
The Aquant works by radio frequency (RF) measurement, a system unique to Protimeter, detecting moisture directly in materials and below wall and floor coverings such as tile, wood and vinyl. Its pinless measurement reaches up to 3/4 in (19 mm) deep on a relative scale of 60 to 1000, so it leaves no pin marks and is not adversely affected by surface moisture such as condensation. A dual LCD and LED display makes readings easy to take, with colour-changing LEDs showing the moisture condition at a glance: green for dry, yellow for at risk and red for wet.
Bluetooth lets readings save to the Protimeter Connect App for recording and reporting. The Protimeter BLD5765 Aquant Moisture Meter weighs 195 g with its 9 V battery, measures 190 x 70 x 49 mm and carries a 24-month warranty on mechanical or manufacturing defects. It is used in damage restoration, building surveying and flooring inspection. Supplied by BAMR, South Africa's authorised Protimeter distributor.

When to use the Protimeter Aquant
You are tracing moisture in a building and do not want to leave pin marks in finished surfaces. The Aquant uses Protimeter's RF system to read moisture up to 19mm below and behind coverings such as tile, wood and vinyl, so you can survey damp without lifting or piercing the surface.
- 1Reads below the surfaceIt detects moisture up to 19mm deep and behind wall and floor coverings, so you can find damp under tile, wood or vinyl without lifting them first.
- 2Ignores surface condensationIt is not adversely affected by surface moisture such as condensation, so a damp top layer does not throw off the reading of the material beneath.
- 3Colour-coded condition at a glanceGreen, yellow and red LEDs show dry, at-risk and wet states, so an inspector can walk a surface quickly and flag the problem zones without reading numbers.
- 4No marks on finished surfacesNon-invasive measurement leaves no pin holes, which matters when surveying finished or occupied rooms where damage is not acceptable.

Features
Detects moisture directly in materials and below wall and floor coverings such as tile, wood & vinyl Not adversely affected by surface moisture such as condensation Bluetooth capabilities to save readings to the Protimeter Connect App Dual display LCD and LED for easy reading (now even larger) Color changing LEDs to show moisture condition green (dry), yellow (at risk) and red (wet) Non-invasive measuring - no pin marks left 3 times longer battery life Industry leading 2-year warranty The Protimeter Aquant is the ideal instrument for checking the relative moisture condition of building elements such as solid walls and floors prior to more rigorous and time-consuming investigative procedures that may be required. The Protimeter Aquant can be used to detect the presence of moisture behind floor and wall coverings such as ceramic tile and vinyl floor coverings.
It can also be used for surveying GRP boat hulls for the early detection of damp spots that could lead to blistering caused by osmosis. Search Mode (non-invasive) The digital display is synchronized with a color-coded LED scale.
The display shows the relative moisture level of the material under investigation on a scale of 0-999 and the colour coded LED scale indicates the material's moisture condition at a glance - dry, borderline and damp.
Simple Operation
To use, simply hold against the surface of the material under investigation. The relative moisture level is measured by radio frequency to a nominal depth of 10-20mm.
There are no needles to mark the surface and the Aquant is not adversely affected by moisture.
