Parameters when choosing

There are devices that measure the percentage of humidity, the amount of vapor, and the dew point; therefore, their designs and methods of operation vary. The following are hygrometers:

• Hair type. They have a thin hair built into them, which changes length and position when in contact with water: the higher the humidity, the more it deviates.
• Weight type. Devices of this type have tubes into which a hygroscopic substance is poured. Moisture from the air passed through it settles on these tubes, the substance absorbs them, and therefore changes weight. The indicator of the humidity level will be the difference between its masses before and after measurements.
• Membrane type. These devices have a special film/membrane of organic type, which changes its size with increasing humidity.
• Mechanical type. These devices have ceramic or metal components, and the humidity level is detected by changing their electrical resistance.
• Condensation type. In these devices, condensate settles on the surface, the amount of which they record.
• Electronic type. These devices can track both the dew point and the electrical conductivity of the air, and the electrical resistance of salts.
• Psychometric type. It consists of two thermometers, one of which is placed in a humid environment.

Determine the purpose of the hygrometer before selecting it. For instance, apartments and greenhouses can use devices with a measurement range of up to 70%, but a bathhouse will need a range of up to 100%.

Compared to electronic devices, which measure humidity, temperature, and air pressure in addition to having a clock and an alarm clock built in, mechanical devices are less expensive and more appropriate for use at home. However, they are less functional.

For private use

The following kinds of equipment can be used to measure humidity in homes, bathrooms, or greenhouses:

• Membranes. Organic film in their body is associated with the scale. The higher the humidity in the room, the longer it becomes more, moving the arrow on the scale. These devices are easy to use, inexpensive, can even measure humidity at low temperatures, but do not have 100 % accuracy.
• Ceramic. These mechanical devices are suitable for determining humidity in residential premises, and the indicators always indicate in real time. In these hygrometers there are ceramic porous elements that react sensitively to moisture, absorbing it from the air. If there are a lot of it, then they are moistened and when the current pulses pass through them show a low level of resistance. The arrow of the device reacts precisely to the latter, changing its position on the scale. These devices are not the most accurate, but they are built into climate control systems.
• Electronic. These devices are characterized by good accuracy, suitable for private and professional use. Small household electronic hygrometers. They have a built-in plate covered with electrical insulation, on top of which lithium chloride is applied. The latter changes its electrical resistance values ​​with increasing humidity. The device reads these changes and displays the result on the screen. Electronic devices are convenient because they show not only humidity, but also air temperature, and more expensive models are equipped with a barometer and a clock.

For personal use, you should consider the following factors when selecting a hygrometer:

• width of the temperature measurement range;
• humidity measurement range;
• ease of use and operating principle.

For professional

In laboratories and industry, hygrometers come in the following varieties:

• Weighing. These are the most accurate devices. Their closed, interconnected tubes contain a hygroscopic substance. To check the humidity level, it is enough to open the tubes so that air can pass through them. If there is moisture in it, the substance will absorb it, which will lead to an increase in its weight. The result is the difference in weight before opening and after closing the tubes. To find out the exact humidity, you should take into account not only the weight of the hygrometer, but also the volume of air that has passed through it. After performing mathematical calculations, you will get the result.
• Condensation. This device is equipped with a mirror. To find out the humidity, you need to record its temperature, then cool it so that condensation appears on it, and measure it again. By comparing the temperature difference with the table, you can find out the humidity level.
• Hair. They are used in laboratories. It is based on defatted hair, which lengthens in a humid environment, showing the humidity level.
• Psychometric. This type of measuring device is most often used in enterprises. Its task is to calculate the difference between dry and humid air.
• Film (membrane). They are used in industry when it is necessary to check the humidity of the environment in low temperature conditions.
