Moisture meter for building materials and masonry

If moisture penetrates into masonry, wooden structures or other building materials, this can have considerable consequences. For example, the materials can be massively damaged in their structure due to the increased water content. In addition, health hazards for people, for example through the formation of mould, should not be neglected. To counteract this, you can purchase a suitable moisture measuring device from Our experts will be happy to advise you on your choice from our large portfolio of high-quality devices.

When is a building material moisture meter used?

A building material moisture meter can be used in both private and professional environments. On the one hand, buildings and building components such as walls or floors can be tested for their moisture content.

On the other hand, the instrument is also used to analyse the building materials themselves. This is of great importance for quality assurance in the production and storage of building materials. Typical applications are, for example:

  • Assessment of mould in buildings
  • Assessment and cause identification of dampness in walls, masonry or floors
  • Assessment and acceptance of buildings
  • Assessment of building floors
  • Quality control of building materials and raw materials
  • Inspection of stored building materials
  • Checking the moisture content of wood

Moisture meters in the product range

The product range at contains mainly moisture meters from the manufacturer TFA Dostmann. You can choose from the following high-quality measuring instruments.

DOSTMANN Material Moisture Meter HumidCheck Non-Contact

This measuring instrument is characterised by a measuring ball which can be placed directly on the surface to be tested. No additional electrodes need to be installed. Despite this function, the 200 g device can measure up to 40 mm in the wall. The results are given in digits.

DOSTMANN HumidCheck Mini material moisture meter

The small compact instrument from Dostmann is a lightweight at 50 g. It can measure moisture in wood from 6-4 mm. It can determine moisture in wood from 6-42 % and in building materials from 0.2-2 %. The moisture values are given in percent.

DOSTMANN HumidCheck Mini II material moisture meter

This moisture meter has a measuring range of 6-48 % for wood and 0.1-11 % for building materials. After inserting the measuring electrodes, the 60 g instrument is immediately ready for use. The moisture values are given as a percentage.

DOSTMANN HumidCheck material moisture meter

This basic instrument can determine moisture contents of 6-44 % in wood and 0.2-2 % in building materials . For both scales, the values are given as percentages. With a handle clip and an automatic function test, the instrument weighing approx. 100 g can be used immediately.

DOSTMANN HumidCheck Pro material moisture meter

This expert instrument can determine the moisture content in wood in the range 6-9.9 %. The measured moisture is indicated in digits. The instrument weighs approx. 175 g and has additional external room humidity and temperature sensors.

How a moisture meter works

Most moisture meters are based on the same measuring principle of so-called capacitive measurement. Here, the electrical properties of the material, wall or floor to be examined are determined. For this purpose, the moisture meter sends an electrical impulse through the object to be measured.

In the second step, the measuring device measures what happens with the electrical impulse . If it is not transmitted, the material is an insulator. For the measurement it is absolutely necessary that the measuring device and the material to be examined have contact. However, with individual instruments, such as the No-Contact model from Dostmann, no additional electrodes need to be added in order to carry out measurements.

Since water is particularly conductive and has a particularly high dielectric constant, it significantly alters the electrical conductivity of the object under investigation. Therefore, the measured electrical properties can be used to draw very precise conclusions about the moisture content of the substance under investigation.

Selecting a moisture meter: What should you look out for?

Since the instruments can differ in various properties, there are a number of points to consider when selecting the right moisture measuring instrument. The following criteria may help you in your purchase decision:

Material suitability

Not all measuring devices are suitable for all materials. For example, certain building materials or wood may require different devices. They also differ in the range over which they can measure moisture contentand in their accuracy.

Required penetration depth

The penetration depth indicates how deep the probe should penetrate into the object to be tested. Some devices must be able to penetrate the material in order to measure well, for others a surface contact is sufficient. In the case of sensitive surfaces, deep penetration is often not desirable, but a superficial measurement is often at the expense of accuracy.

Measurement display

There are usually two options for displaying the measured values: The indication in percent or the indication in absolute numbers also called digits. Some instruments are also able to display both. Since the absolute numerical value is much more accurate than the percentage value, the display as a numerical value is preferred in the professional field.

Handling and operability

If you intend to use the measuring instrument frequently, you should not neglect aspects such as weight, ergonomics and ease of use. Small and light devices that can be operated with one hand and on which the reading is easy to read are ideal.
