Protimeter BLD5365 Surveymaster Dual-Function Moisture Meter
The Protimeter BLD5365 Surveymaster is a dual function moisture meter that combines pin type and non invasive measurement in one rugged handheld instrument. It is built for building professionals who need to find measure, and track moisture in walls, floors, and other structures, and it has long been one of the best known meters in the trade. The ergonomic design allows easy one handed operation.
Key Features Protimeter BLD5365
- Two modes of operation: Search mode detects moisture below the surface without damaging it and Measure mode takes a direct pin reading
- Non-invasive Search mode: detects moisture up to about 20 mm (3/4 in) below the surface so you can survey walls and floors rapidly without pushing pins into finishes
- Unaffected by surface moisture: the non invasive reading is not thrown off by dampness on the surface helping you separate surface condensation from deeper moisture problems
- Pin moisture measurement: use the built in pin electrodes or plug in auxiliary probes for readings at depth such as the supplied heavy duty two pin probe (BLD5060)
- Wide pin range: 8% to 99% WME, with readings above 30% shown as relative values
- Clear dual display: a digital LCD plus a scale of color coded LEDs for an instant moisture condition read out
- Real wood moisture content: shows actual moisture content for wood and Wood Moisture Equivalent (WME) values for other non conductive porous building materials
- Audible tone: can be switched on or off by the user
- Auto-off function: conserves battery life
- Rugged and compact: about 7.5 × 2.75 × 1.9 in, and roughly 225 g with battery
- Accessory compatible: works with a wide range of plug-in probes and electrodes including a hammer electrode (optional)
- Warranty: Protimeter instruments carry a two year manufacturer warranty
Typical Applications
- Building surveys and damp investigations
- Moisture checks during new build and refurbishment
- Concrete and wood floor moisture assessment
- Finding moisture behind wall and floor coverings such as tile and vinyl
- Mapping the extent of moisture penetration and monitoring changes over time
- Insurance, restoration and property inspection work
Why Choose It
The Protimeter BLD5365 Surveymaster lets you scan quickly in Search mode then confirm what you’ve found with a pin reading all with one meter. That combination helps you tell surface moisture from hidden problems gives instant easy to read results and holds up to the demands of daily site use.
