What is a moisture meter, and what do I need it for?

As the name suggests, a moisture meter measures the level of moisture in the air or in certain places in your home. Especially with the use of construction dryers, these meters can be very important.

Depending on the season and the use of heating and air conditioning, the humidity can change. As a result, it is not easy to keep the value of humidity in the air optimal.

Did you know that higher humidity leads to mold growth?
The danger of mold often arises in winter. Since you rarely open the windows, the humidity in the air increases and so condensation forms.

For this reason, it makes sense to use a humidity meter. This way you have the possibility to always have an overview of the humidity in different rooms.

Moisture meters are especially useful in the use of dryers and dehumidifiers. So you always know how thoroughly they work and what humidity value was reached.


What types of moisture meters are there?

There are different variants of moisture meters, which are all suitable for different applications. Moisture meters differ primarily in their scope of application.
For example, there are devices that are specifically designed to measure the moisture in the air. Others measure the moisture content in the wall or other places.

There are several types of moisture meter:

  • The temperature hygrometer.
    To measure the total humidity of the room.
  • Moisture indicator.
    Shows the moisture content of certain places such as walls, wood, etc.
  • Psychrometer.
    Determines air humidity parameters and is used in meteorology.
  • Moisture meter.
    Helps with microwave humidity measurements in hard-to-reach places up to 30 cm deep.
  • Pyrometer.
    Determines the moisture content of the material in/on components, and most professional applications.

For this reason, you should be aware in advance for which purpose you want to use your moisture meter. Furthermore, combo devices are also available, which have several functions and are thus suitable for different applications.

What should you look for when buying the moisture meter?

To find the best device for individual use, you must first familiarize yourself with the differences between analog and digital hygrometers.

When buying should pay attention to the following:

  • Material / Size / Weight.

The material is not one of the decisive criteria when choosing a hygrometer, but the durability is worth mentioning. Most hygrometers have a plastic housing and a plastic glass cover. High-quality hygrometers are made of stainless steel, for example.

As for the size, the bigger, the better. The reason is the readability of the display. Logically, larger displays are more visible. Size also matters if you want to hang the hygrometer on the wall, for example, and have limited space.

The weight is strongly dependent on the material. Plastic is lighter than stainless steel, so these hygrometers are also lighter. You can assume that heavier hygrometers tend to have a higher build quality.

  • Measuring range.

The measuring range is probably the most important buying criterion when it comes to humidity meters. This criterion determines the range over which the moisture in the air or in a particular material can be measured.

The amount of moisture in the air or in a particular material, such as wood, is expressed in several ways. One way is to express it as a percentage. In this case, a proportional amount of moisture is displayed on the instrument during measurement. This option is mainly used to indicate the humidity of the air.

The second option is to express it in numbers, which is used to measure the moisture content of wood or building materials. Here, the amount of moisture is indicated by a whole number.

In general, the higher the measuring range, the higher the quality of the device. Of course, this is also reflected in the price.

The humidity in a typical room should be between 40-60%.

Some hygrometers also have a built-in thermometer, which is a useful and useful feature. Humidity is important for an optimal indoor environment, but the temperature is just as important.

The temperature measurement range depends on the intended use. If the device is also used outdoors, the hygrometer should also display minus values. The larger the measuring range, the better, this also applies to this location.

The humidity measuring range is one of the most important criteria in the purchase decision. A good device is at least always characterized by the fact that it has a measuring range between zero and 100.

  • Battery.

Digital hygrometers, unlike analog devices, must be powered either by electricity or by a battery. Therefore, it is important to know what batteries the instrument requires and to always have them on hand.

Many hygrometers are powered by push-button batteries, which have the advantage of being much lighter. However, they are also more expensive than regular batteries. Therefore, we recommend choosing a hygrometer that runs on regular batteries (AA or AAA). They are cheaper.

  • Other features.

Many hygrometers today are 2-in-1 products. That is, in addition to humidity measurement, they also display temperature measurement, have a built-in barometer or anemometer, and have an interesting hold function.

In addition, some also have radio clocks, alarms, or humidity sensors. Which function is relevant to you depends on your purpose. So, it is possible that a hygrometer without additional functions is the perfect device for you.

The hold function is a very practical detail of humidity meters. This function is especially useful in hard-to-reach places and dark corners.

With the hold function, you can “freeze” the current measured value and then read it on the display. In this way, you can also take measurements in difficult places. However, this function is available on the vast majority of devices.

Moisture meters are suitable for professional and private use. There are different types of hygrometers, which differ in their application. Hygrometers are available in both analog and digital form. Digital hygrometers require batteries, unlike analog ones.

The price of hygrometers depends on the performance of the device and the purpose for which it is used. In most cases, digital devices are more expensive than analog ones.

The moisture meter is used to measure the humidity of the air as well as solid materials such as concrete or wood. It also helps to prevent the occurrence and spread of mold in time.

FAQs- The Best Moisture Meter In Comparison

✅ How do I calibrate the moisture meter?

To calibrate the moisture meter, i.e. to set it correctly, you must know the humidity value in the immediate environment. If you know this value, set the pointer of the moisture meter exactly to this number, and it will be set correctly.

It is recommended that the instrument be calibrated every fourth to sixth month to maintain an accurate reading. However, this is not always stated in the operating instructions. If the hygrometer is transported, you may need to readjust it.

✅ Where should the moisture meter be placed?

You may be wondering where the best place for the moisture meter is. First, all moisture meters are suitable for indoor use, but only a few are designed for outdoor use. So if you need outdoor humidity information as well, you will need a weatherproof model for that. They will come with a label.

The best place in the room is a central, highly visible place. Logically, a hygrometer is useful in poorly ventilated and often cool rooms. Never place the moisture meter at a window behind a curtain or directly above a heater. These influences will skew the results. If you take these things into account, you have already found the ideal location.

What should be the recommended temperature and humidity for each room?
The temperature and humidity in your own home can vary depending on your preferences. Also, there are no exact values that you should necessarily stick to.

However, there are recommended values for temperature and humidity in different living areas. They are to ensure that your respiratory system is not irritated and mold growth is prevented.

✅ How does the moisture meter work?

Moisture meters are relatively small and handy devices. Operation is usually relatively simple and straightforward.

Most models are battery operated and have a small digital display on which the measurement data can be read. Depending on the type of moisture meter, a different measurement method is used.

Most models have electrodes that measure the moisture content in the air or in a specific material. The measured value is shown on the display for a short time.

Depending on the model, additional functions such as saving the measured value or a “Hold” button are available.

✅ How accurate are the moisture meters?

The accuracy of the measured values depends on a number of factors. Depending on the model and type of use, readings may vary in accuracy.

In general, however, moisture meters are very accurate. The readings are ideal for the vast majority of applications. However, some applications place higher demands on the accuracy of the measured values.

Here, the more expensive and better the device, the more accurate the measured values.
