digital Wood Moisture & Damp meters

We offer a wide variety of easy to use hand held digital moisture & damp meters for building surveyors, industrial flooring contractors, timber producers, building pathologists & craftsmen.

We offer various traditional two pin resistive type digital moisture/damp meters & also non intrusive ball head type digital moisture meter using the dialectic measurement technique for measuring relative moisture content just below the surface.

If deeper penetration measurements are required, the T600 moisture/damp meter uses low power microwave signal technology for sub surface relative moisture measurement in walls and floors up to a depth of 30cm. This type of material moisture measurement technique is unaffected by salts contained within the material being measured.

For hobbyist and craft applications, a selection low cost moisture meters are available.

Engineers wanting just one instrument to cover may applications, the multi function T2000S has a BNC input for resistance type probes & also a digital SDI input for Trotec digital SDI probes for measurement of temperature, relative humidity, airflow, wood moisture (incorporating wood species calibration curves with temperature correction) & relative moisture.

The T250 provides surface temperature measurment & calculates dew point temperature, in addition to relative humidity, all in one instrument. A wide range of accessories & moisture probes are available for use with either the T500 or T2000 series to extend the functionality of these instruments.

We also offer a low cost range of moisture/damp meters meters for less demanding applications.

The Trotec T250 combines a digital thermo-hygrometer with a laser pyrometer and dew point alarm in a single instrument.


Measure surface temperature with the built in infrared non contact pyrometer or automatically calculate surface dew point temperature. The variable dew point alarm enables rapid surface scanning of walls to detect areas requiring remedial attention.

The Trotec T500 is a professional hand-held measuring instrument for the precise determination of the moisture content in wood & soft building materials using the resistance method.

Measures wood moisture accurately by applying the correct wood species calibration curve obtained from the wood species compendium supplied with the instrument.

Correction of surface temperature/ambient temperature difference is done by inputting the surface temperature.

Where tougher materials require the use of a "hammer" type probe etc., the T500 has an optional adapter kit to connect all types of resistance electrodes to the T500.

Using the TS adaptor set and the corresponding connecting cable you can connect all MultiMeasure resistance electrodes to the T500 for measuring wood and building moisture, greatly extending the usability of the T500 and making your investment go further.

The Trotec T600 is a professional hand-held instrument for rapid non-intrusive measurement of sub-surface relative moisture content in plaster and other soft building materials.

By means of microwave technology it is possible to detect distributions of moisture content at a penetration depth of up to 300 mm.

Another advantage of this technology is its independence from the level of salt content present in the material. It therefore makes no difference to the microwave technique whether an older or a new building are being surveyed for hidden dampness.

The Trotec T650 is a professional hand-held instrument for fast, non-destructive determination of relative moisture content distributions up to a depth of 4 cm below the surface.

Built in variable audible alarm for rapid scanning of large surface areas.

Why measure damp/moisture content

Here are some examples of problems that have been caused by water ingress in materials & also moisture in the air (water vapour) due to lack of adequate ventilation, damaged vapour barriers or bridging of damp proof membrane.




Rising damp is the upward movement of ground water through the pores of a permeable masonry wall via a process called capillarity. Capillarity is the same process that enables the movement of water from tree roots to tree tops via intricately stacked hollow cells despite the counteractive force of gravity

Rising damp typically occurs if the built-in damp proof course is bridged, for example by a change in ground level, or if the damp course is damaged, for example by a structural alteration or a chemical reaction. In such cases rising damp may become a problem if it is likely to affect vulnerable materials or finishes that are in contact with the wall. For example if the damp has potential to rot joists, skirting boards or the bottom of door frames or if it causes wall plaster or wall coverings to deteriorate or become stained.



Penetrating damp occurs where water soaks into the living accommodation of the building, either above or below ground level. Above ground level, penetrating damp is usually due to one or more building maintenance defects. An example of this could be a leaking rainwater pipe which, combined with dilapidated pointing, frost damaged bricks or faulty joints between window & walls, has allowed damp to soak completely through the wall.



Damp mould on walls and ceilings can be caused by the air held inside a building, which often incorporates high moisture content due to cooking, bathing, drying clothes etc. As the temperature of humid air drops, its capacity to retain its water vapour content reduces and once a dew point is reached, the condensate is deposited onto surfaces that are cooler than the moisture laden air.

Condensation damp is immediately obvious on non-porous surfaces such as glass & ceramics but less noticeable on porous surfaces such as plasterboards, wall plaster and timber, which simply absorb the damp and encourage black mould growth, causing a potential health hazard if the mould spores are inhaled or structural collapse in the case of rotten roof joists
