How to choose a hygrometer to calculate humidity

A hygrometer is intended to measure humidity and monitor its level in the air. It may be necessary to use it for several reasons which may be health or economic. There are several types of hygrometer which come in several forms and at different prices. With this vast choice, it can be difficult to find your way around and choose the hygrometer that best suits your needs.

How does a hygrometer work?

For various reasons, it can sometimes be complicated to choose the right hygrometer for domestic use. Because there are different types of hygrometers.

The humidity meter can be analog or digital. When it is analog, the operation is mechanical. These are needle, metal spring or hair hygrometers. Electronic hygrometers, on the other hand, work using humidity sensors and the results are displayed on a dial.

Why use a hygrometer?

A hygrometer assesses the relative humidity level in a room as effectively as possible. It is a device that allows you to keep an eye on this rate and adjust the temperature accordingly, the relative humidity varying according to temperature changes.

The relative humidity rate is a decreasing function of increasing temperature. A low temperature therefore implies an increase in humidity and vice versa. However, excess humidity, for example, causes the proliferation of bacteria, mold or fungi and has consequences which can be very harmful to health. The humidity meter is therefore important for monitoring the constant that is the moisture content of the air. It directs you to the need to acquire an air humidifier or a dehumidifier depending on the case.

What are the top 3 best hygrometers?

We selected these three humidity meters according to objective evaluation criteria:

The ThermoPro TP55 hygrometer

This indoor and outdoor model of moisture meter is simply the best value for money. He is excellent. It has a backlit LCD screen which turns off after a period of inactivity, then a touch screen which greatly facilitates ergonomics. The display also offers a projection in the form of arrows which show the trends in the humidity and temperature constants . It has an accuracy of ±5 RH and weighs only 145 grams.

The AMIR hygrometer

Available in several versions, this wireless moisture meter offers an accuracy of 5% with automatic data updating every 60 seconds. The sensor and the screen can connect within a distance of between 30 and 100 meters.

The Sodial hygrometer

It presents good value for money. It is a compact piece of equipment that can also be used as a thermometer. The Sodial digital humidity meter is relatively durable and suitable for people for whom the concept of hygrometry is new thanks to its ease of use and an accuracy of ±5 RH.

In summary, the choice depends on your needs and your budget . Some humidity meters offer very high precision in addition to being used wirelessly and within a radius of several tens of meters, while others rely on the ergonomics of their screen to offer you an excellent user experience to combat humidity of a place .
