Moisture Meters Buyer Guide


Before buying a hygrometer, it is good to know if, in addition to the humidity and temperature values, you also need the detection of other data concerning the environment or the object to be analyzed.

On the market, there are multifunction models that are able to acquire other values ​​as well, such as the PH level of a material, the illumination of a field, the acoustic quality of an area, or a room.

If you need to use the hygrometer in the home, it will not be necessary to spend too much on an expensive tester, but if instead, you have to use it for professional reasons, then you will have to opt for a more sophisticated model with a particularly wide measuring range.

In fact, the standard detection range for a professional hygrometer is generally from -30 ° C to 70 ° C for temperature and from 5% to 98% for humidity.

In addition, the tolerance level for measuring a professional model should be zero, precisely because greater precision is needed.


Like any self-respecting electronic device, many hygrometers are also equipped with wireless functionality. It is possible to remotely control the humidity level of the house, so as to adjust it according to one’s own needs with specific tools such as air conditioners, dehumidifiers, and humidifiers.

The wireless hygrometers can be controlled directly with the app, where you can select the settings from your smartphone or tablet. It is possible to activate an SMS alert service, which warns the user when there are significant changes in the humidity level.

Some models send the warning message not only to the primary user but also to other indicated persons. For example, if the homeowner fails to receive the alert, it will be sent to the children, partner, or other people living in the house.


The choice of hygrometers also depends on additional features. In addition to measuring humidity, some models are also capable of monitoring temperature.

In this case, we speak of Thermo hygrometers, and the price tends to rise. Modern technologies, however, now allow you to have Thermo hygrometers even at a good price if you do not require great precision.

The more precise models that combine the two functions are instead indicated above all for professional use.

The functions also include the display, which can give additional indications such as the time, date, and precisely the temperature. A backlit display can be very useful for reading the humidity level even in a dark room.

Another feature to consider is data logging. Some models have rather low memory and are able to detect data from a single day. This function is not important for those who stay at home all day and can monitor the hygrometer constantly. Instead, it is essential for those who stay out all day.

In this case, it is advisable to purchase a hygrometer capable of storing the measurements of several months, so as to calibrate a uniform humidity level for your needs.

Method of Use

Knowing the humidity level of the air inside your house could be very useful for understanding certain things, such as in case you notice strange odors of mold or the humidity level is too high; then you will have to ventilate the room or find any water infiltration.

In this way, you will intervene in advance saving time and money due to a structural or environmental anomaly. Thanks to this tool you will be able to adjust the boiler to the right level of heat emission, avoiding that the air is too humid or too dry.

Furthermore, if you are a cigar enthusiast, you will surely know that these are kept well, always maintaining the right level of humidity. This value is even more important in a museum, in a library or in an archive, where paper documents and works of art are kept.

The applications of a hygrometer are really many and range from agriculture to construction depending on the type of functions that the device offers.

Structure and Handle

Another important factor to consider before purchasing a moisture meter is the quality of the materials. Make sure that the tester is well made and that the manufacturer is reliable, always reading the technical data sheets of the various products.

It is not said that the most expensive hygrometer is the best and for this, it is useful to evaluate the reviews of the various users.

The device must have a clear and clearly legible display, which gives the opportunity to always have an eye on all the values ​​acquired. The interface must also be practical and intuitive, so as not to waste too much time during the settings.

The handle of the instrument must be comfortable and easy to handle to facilitate you during the various measurements and the data detection probes must be solid and robust.

In fact, there are some hygrometers which, thanks to the pointed pins, are able to penetrate the wood to acquire the internal level of humidity.

The Humidity in The House

Let’s focus on the level of humidity that should be in the house. The values ​​considered optimal oscillate between 40 and 55%. If the rate is not within this range, then there are two things: the climate is too dry or too humid.

In the first case, the critical threshold is 20% of humidity while in the second it is 60%. In this case, the consequences are condensation and mold formation.

The Position

For the correct operation of the moisture meter, attention must be paid to its position. Avoid placing it in a corner, rather than position yourself in a well-ventilated place.

Attention must also be paid to the height: the instrument must be between 100 and 150 cm from the ground. Keep in mind that the humidity varies between morning, afternoon, and evening.

The Humidity Alarm

It can be very important to be aware of when the humidity in the air exceeds a certain threshold. To do this, many meters are equipped with an alarm that must be set according to your needs, taking into account the maximum humidity limit that you consider tolerable.

Mold Danger

Mold is far from healthy for health, some models of hygrometers allow you to set a risk warning. If the threshold is exceeded, the user will be immediately notified by the instrument.

But why is it so important to prevent mold growth, in addition, of course, to wanting to preserve the aesthetics of the home? Mold can cause several respiratory problems. As it is easy to imagine, the subjects most sensitive to the problem are children.
