Sometimes inconspicuous devices play a very important role in both the heavy and food industries. A perfect example of this is a humidity meter. For example, you can choose a wood meter, but there are also models available that measure the moisture of other materials. These technologically advanced devices are equipped with an integrated sensor that reaches deep into the material and checks the moisture of the raw material. It's worth learning more about this.

Types of humidity meters
A hygrometer is, of course, a humidity meter . It is used to measure humidity, but also temperature and fiber density. This type of capacitive devices are selected according to the type of material. Thanks to moisture meters, you can check, for example, the strength properties and hygroscopicity of wood. Material measurements are very reliable. By checking the humidity level of e.g. building materials, you can find out whether they will perform well in the most demanding conditions. In many cases, the moisture content should not be high, as it affects the strength parameters and the entire structure may not be stable. There are different types of humidity meters.
You can choose, for example, a wood moisture meter. You should know that these models can also be divided according to the measurement method. We distinguish resistive and capacitive devices. In the case of the former, we insert electrodes into the wood to measure the resistance of the material. The lower the resistance, the more moisture there is, of course. In turn, a capacitive meter uses the change in electrical capacitance that occurs between two electrodes. They are placed on the surface of the wood. There are also concrete moisture meters that use the phenomenon of electrical impedance.
This means that they emit an electrical impulse that then returns. However, these devices are not the most precise. The next model is an air humidity meter. In this case, it is characterized by high precision because it uses electrical resistance and conductivity. Its measurements appear on the display. You can also opt for a grain moisture meter that uses electrical resistance.
How does a humidity meter work?
Humidity measurement allows you to determine the technical parameters of a given material. For wood meters, humidity largely depends on the tree species. Both capacitive and resistance meters contain two electrodes that must be inserted to a specific depth, usually two centimeters. On this basis, you can compare the parameters of a given wood. Of course, the measurement uses the ambient temperature. The appropriate measurement depth allows for truly precise calculations. In the case of wood, it does not have to exceed 2 cm.
Resistance models are certainly reliable and considered very accurate. The humidity meter works on a simple principle, namely it uses the phenomenon of inhibiting evaporation by humid air. Then it is accelerated by dry air. So the rule is simple, the higher the air humidity, the lower the temperature the meter shows. A dry-bulb thermometer checks the ambient temperature. From the differences, moisture can be calculated. Meters equipped with electrodes operate effectively even in difficult conditions. Effective measurement comparison also allows you to check strength parameters. The use of the meter in many industries is therefore advisable.
How to properly measure humidity levels with a hygrometer?
To measure the humidity level with a hygrometer, you need to set it appropriately. This means that the temperature should be between 19 and 21 degrees. You then need to adjust the hygrometer as quickly as possible so that the reading is 75%. You can insert it deep into the ground and then read the result on a given scale, which is 10 points. In some cases, it is necessary to calibrate the device, but when choosing products of the highest quality, you can skip this step.
In what construction works can a humidity meter be useful?
The humidity meter is widely used in the construction industry. They can be used to determine the moisture level of walls, floors, but also insulation layers and wooden and wood-based materials. Thanks to this, employees can verify whether it will be necessary to dry the materials, but also to use additional insulation. Thanks to the meters, you can measure almost any material without fear of damaging it. For example, you can choose products based on the resistive principle and equipped with special probes.
Thanks to this, you can even check humidity in insulation zones or hard-to-reach places. You can also choose products that are suitable for measuring the humidity of building materials and insulating materials. Using them, you can check the moisture content of gypsum or mixed plasters, and as we know, this is important for work efficiency.
If you choose models with thin, insulated tips, you will even check the material located on the facade or thermal insulation. These devices are also recommended for drying work, so they are used in both the construction and industrial sectors. They use the dielectric method. A moisture meter is also recommended for checking concrete. Universal models work perfectly in this case. Thanks to the appropriate moisture content of the concrete, the material is resistant to loads and sets very quickly.
How high should the air humidity in the room be?
Excess moisture is harmful. Indeed, if there is a high level of it in the interior, fungus or mold often appears on the walls. This is dangerous because it promotes the growth of microorganisms and bacteria. Please also note an important fact: staying in such rooms increases the risk of respiratory diseases. Additionally, people struggling with allergies or asthma may experience more severe symptoms. In turn, too low humidity causes a scratchy throat and drying of the nasal mucosa or eyes.
So what should the air humidity be? Well, the best one for health is one that ranges from 40 to 60%. At the same time, there is a relationship between temperature and humidity. Well, the higher the temperature, the lower the humidity should be. In turn, in the case of lower temperatures, the humidity should be higher. If the temperature in the room is around 19-20 degrees, it is best for the humidity to be between 55 and 60%. If the temperature is higher, i.e. 21-22 degrees Celsius, then the humidity should be from 40 to 45%. This level of humidity is best for your health and allows you to focus.
