Protimeter SurveyMaster Dual-Function Moisture Meter

Protimeter SurveyMaster Dual-Function Moisture Meter

The SurveyMaster is the original dual-function moisture meter: pin measurement and non-invasive scanning in one instrument, so you can map the extent of a problem without marking a surface and then quantify it where it matters. This is the 2024 model, with a larger display, longer battery life and Bluetooth to the Protimeter Connect app.

Two modes, and why you need both

Non-invasive search mode

Reads to about 19 mm below the surface using radio frequency, on a relative 60 to 999 scale. Leaves no marks, so it suits finished surfaces, tiled areas and pre-purchase inspection. Surface moisture does not distort the reading.

It responds to anything conductive behind the surface, not only water — reinforcing mesh, foil-backed insulation, metal lath, pipework and wiring all read high on dry material. Confirm anything unexpected with pins.

Pin measure mode

Measures 6% to 99% WME where the pins make contact, to a maximum needle depth of 10 mm. This is the mode that quantifies moisture and tracks a structure drying day by day. Plug-in probes extend it to depth.

Reference mode

Protimeter's patented reference mode works in both pin and search modes. Measure a dry standard — known-dry material of the same construction — hold the button until the reading stores, and every subsequent reading is then displayed alongside a second figure showing how far above or below that baseline it sits.

This is the correct way to use a moisture meter on an unfamiliar building. An absolute number means little without knowing what dry looks like in that material; the difference from a dry standard means a great deal.

What is new in the 2024 model

• Larger display
• Battery life approximately three times longer, on 2 × AA
• Automatic WME calibration check every 50 power cycles
• User field calibration of the non-invasive mode
• Bluetooth connectivity to the Protimeter Connect app, with readings saved and downloaded with a time and date stamp
• Over-the-air firmware upgrade and a multilingual interface

Specifications

What is in the box

• SurveyMaster instrument
• Carry pouch and wrist strap

Applications

• Building survey and pre-purchase inspection
• Fire and flood restoration — mapping intrusion, then documenting the drying curve
• Concrete and timber floors, subfloors and joists

• Mini extension pin probe (BLD5079)
• Heavy duty hammer electrode (BLD5055) — drives insulated needles into timber at depth
• Deep wall probes, 130 mm (BLD5018) and 360 mm (BLD5019) — readings inside walls and voids. Protimeter also lists a 240 mm version, BLD5020, which is not stocked in Australia
• EIFS probe (BLD5070) — profile readings through render and insulated finish systems
• Baseboard probe (BLD5025) — reads behind skirting without removing it
• Calcheck calibration check device (BLD5086)
• Pin cap (BLD2000CAP), battery cover (BLD2000BAT) and replacement pin needles (BLD0500)

How it compares

The SurveyMaster is also supplied in the Technician's Kit alongside a HygroMaster 2.

Calibration

The instrument runs an automatic WME calibration check periodically, and a check can be run at any time against the Calcheck device. For a documented conformance certificate, twelve months is a sensible starting interval, adjusted to your own work environment and quality procedures. Certification is available in Australia.
