But if you set a goal to pick up the moisture meter yourself, try using the algorithm developed by us.

Define the range of tasks for which you will use a moisture meter. Do not try to cover all spheres of production with one device. Based on this range of tasks, select the type of best wood moisture meters that is more suitable for their solution.
Analyze the change in the moisture content of the wood in the selected range of tasks and determine the range of measurement your instrument should have.
Analyze the requirements of the technological process and normative documents in the accuracy of determining the humidity and its permissible deviations from the regulated values. On the basis of this information, determine the error, which should not exceed the instrument selected by you.
Carefully study the place, process and conditions of use of the device. On the basis of this information, formulate requirements for ergonomics and operating conditions of the device.
Study the proposals and select the devices that meet your requirements. Be sure to pay attention to the warranty and the possibility of servicing the device.
Analyze the prices of the devices you like and select the price category that suits you. Keep in mind that accurate and reliable instruments from famous manufacturers have a high price.
Remember that some of the manufacturer’s claimed parameters may differ from the actual ones. Consult with people who already have experience with the selected device.
Keep in mind that the Ukrainian market has a much larger range of devices than can be found in the available sources of information (and even more so in the article). Do not try to get ahead of the collective work experience and your own experience, listen to the advice of specialists.
If possible, before buying, familiarize yourself with the selected device, evaluate the convenience of its operation.
Try to make an independent choice, using the following background information, tips and a short analytical review of moisture meters presented on the Ukrainian market.

There are two different types of instruments for determining the moisture content and relative humidity of wood – conductive (with electrodes in the form of spikes) and high-frequency (electrodeless, whose operation principle is based on the use of a high-frequency electromagnetic field).

The conductive moisture meter determines the electrical resistance between the electrodes, which are located in the wood at the required depth, and lists it in the amount of moisture or moisture content. And the use of a device or a probe with isolated electrodes makes it possible to determine the moisture content of the wood at a certain depth. Devices of this type have, as a rule, a lower threshold of the measuring range of not less than 4%.

The high-frequency moisture meter determines the dielectric permeability of wood located in a high-frequency electromagnetic field generated by the device and lists it as moisture or moisture content. The result of measuring such a device is more affected by the moisture content of the layers of wood (or other material) located closer to the source of electromagnetic radiation (that is, closer to the surface). Devices of this type are more sensitive than conductive instruments, but it must be borne in mind that the error in the measurement result can cause surface moisture, foreign inclusions or coating of the sample being measured.

Non-contact portable
They are used to check the humidity without damaging the wood. The disadvantage is quite unstable to the measurement of hot materials and a large error in measurements.

In addition, areas with increased resinity of the boards after drying are measured poorly. They are used in the production of molded products and fused products, in places where damage to the material is unacceptable.

Needle-shaped portable
Portable moisture meters can be of several types:

For boards compact pocket with a short needle. Their advantage is mobility, the master can wear it all the time in his pocket. Deficiency, humidity checks on the surface of the board and small traces remaining on the finished product. Judging by the reviews, and take into account your experience, we can say that these are the best instruments for measuring boards. They are compact and precise;
