The Protimeter Surveymaster Moisture Meter (part number BLD5375) is a dual-function moisture meter that measures moisture in buildings and related structures using both pin and non-invasive modes. It allows you to assess moisture levels for new and refurbishment work and to diagnose moisture-related problems in existing buildings, where undetected damp drives decay, mould and the failure of finishes and coatings.
Two measurement methods are combined in one instrument of the Protimeter Surveymaster Moisture Meter. Pin mode reads electrical resistance between two pins for moisture content of 7.9% to 99% WME, to a depth of up to 12.5 mm. Non-invasive mode reads relative moisture from 70 to 999 to a depth of up to 20 mm without marking the surface, and is not adversely affected by surface moisture. Results are shown on a backlit digital LCD and on a 60-LED bar that signals Dry (green), At Risk (yellow) or Wet (red), so a surface can be classified at a glance.
The Protimeter Surveymaster Moisture Meter has Bluetooth connectivity to the Protimeter Connect app for saving and downloading time and date stamped readings, plus in-built and periodic WME auto calibration checks, field calibration of the non-invasive mode, over-the-air firmware upgrades and a multilingual interface. The Surveymaster Moisture Meter weighs 225 g, runs on two AA batteries and carries a two-year warranty. Supplied by BAMR, South Africa's authorised distributor.

When to use the Surveymaster Moisture Meter
Use the Surveymaster on a building survey when you need both a non-invasive scan and a pin reading from one meter, with clear dry, at risk and wet bands. It scans up to 20 mm non-invasively and reads up to 12.5 mm on pins, with Bluetooth for recording. The decision is whether your survey needs that dual function rather than a single mode meter.
- 1Two meters in oneNon-invasive scanning finds damp behind a surface and pin mode confirms moisture in the material, so one instrument covers both stages of a survey.
- 2Clear dry, at risk, wet bandsThe colour banded LED scale and indicators give a fast dry, at risk or wet call, which speeds rapid assessment across a property.
- 3Bluetooth recordingBluetooth connectivity logs readings for the report, so survey data does not depend on hand written notes.
- 4Calibration checks built inIn-built and periodic WME auto calibration checks plus field calibration for non-invasive mode help keep readings trustworthy between jobs.
