The Protimeter Mini is a compact, general purpose pin type moisture meter used for assessing the moisture conditions in buildings.
The Protimeter Mini can be used for making rapid moisture assessments in a wide range of building materials including wood, masonry, drywall, plaster and concrete. The instrument measuring pins are small and sharp which means measurements can be taken at the surface with virtually no mark left behind. The numerical values represent the actual percent moisture content of wood (%MC) and the wood moisture equivalent (WME) of other materials. The Protimeter Mini can be used to determine if the fabric of a building is in a dry, borderline or damp condition.
When taking readings in awkward positions, the Protimeter Mini can be used with the included moisture probe and lead. The optional Protimeter Hammer Electrode can also be used with the Protimeter Mini for determining moisture gradients in wood.
Included Deep Wall Probes can be used with Protimeter Mini to measure the moisture level at depth in a wall, irrespective of the surface condition. Deep Wall Probes are very useful accessories when investigating the cause of the moisture problems within buildings.
Features and Benefits

Building Related Questions
What is the Wood Moisture Equivalent (WME) scale as used on Protimeter moisture meters?
- Protimeter moisture meters are calibrated for wood but are also suitable for measuring moisture levels in other materials. They are highly versatile tools for assessing the moisture condition of a wide range of non-conductive materials.
- In wood, the instruments measure the materials actual percent moisture content (%H2O). When testing material other than wood, the meters measure the wood moisture equivalent (WME) value of the material. WME is the moisture level that would be attained by a piece of wood in equilibrium with the material being tested. As the critical moisture levels for wood are known, WME measurements enable the moisture meter user to establish if materials are in a safe air dry, borderline or damp condition.
What is Relative Humidity (%rh)?
- Relative humidity (%rh) is the degree of saturation or the amount of water vapor that air contains relative to the amount it would contain if saturated. This is often expressed as a percentage, so saturated air at a given temperature has 100%rh.
- If air is warmed, the amount of water vapor it could hold at saturation is increased. Consequently, the %rh value falls, even though the actual amount of water remains constant. Similarly, if the air is cooled, the amount of water vapor it can hold is reduced. Consequently, the %rh value rises.
- Condensate forms when there is an excess of water in saturated air.
At what level of WME is a material in a wet or dry condition?
- <18% (Green Zone) - The material is in a Safe Dry condition, moisture related problems of decay/deterioration will not occur.
- 18% - 20% (Yellow Zone) - The material is in a Borderline condition, decay/deterioration may occur under certain conditions.
- > 20% (Red Zone) - The material is in a Wet condition, decay/deterioration is inevitable in time unless the moisture level of the material is reduced.
I suspect my %WME readings in a wall are too high, what should I check?
- has been heavily contaminated by hygroscopic salts, or
- in materials that are conductive by their own nature.
- Artificially high moisture meter readings may be obtained in material that
- In the case of hygroscopic salts, the presence (or otherwise) of nitrates and chlorides should be established when investigating suspected rising dampness situations in particular. This can be achieved with the Protimeter Salts Analysis Kit (PR4900).
- If the material being tested is conductive an alternative moisture measurement technique should be used. A hygrometer could be used to measure the materials ERH, or its actual moisture content could be determined with an Ashworth Instrumentation Speedy tester (see product information).
