Few people know about the existence of such a device as a hygrometer. And, of course, not everyone knows the benefits that can be derived from its use. First of all, it is health, which depends on living conditions and a comfortable microclimate. These are not only indicators of temperature conditions and air pollution, but also humidity parameters. Deviations from optimal values can contribute to the occurrence of serious diseases. This is the main reason why it is worth buying a room hygrometer in every house or apartment, with the help of which ideal conditions will be created for all family members.

Measurement of air humidity in a room: basic methods and devices

Before choosing the optimal moisture meter, you must familiarize yourself with the principles of its operation. The main classification can be distinguished:

hygrometers;
psychrometers.

Despite the common end goals, the principle of operation of a psychrometer and a hygrometer is different.

Can change humidity primitive grandmother's methods - a glass filled with liquid using thermometer or a spruce cone, the scales of which open up if the air is dry.

Hygrometer: what is it

A humidity meter is used to determine a comfortable microclimate in a room. Before deciding which hygrometer to buy for an apartment, it is important to know the basic classification and how each model works.

The devices can be divided into 4 types.

Psychrometer;
hair device;
electronic;
condensing.

The simplest devices use special tables with relative humidity parameters. Modern electronic models work with microcircuits, they independently take data and display them on the display.

Why buy a room hygrometer

Human health depends on many factors. An important role is played by the state of the air, in particular, its humidity... Both high and low humidity are harmful. With increased - the multiplication of viruses and microbes begins. Decreased leads to difficulty breathing, drying out of the mucous membranes.

Modern meters are additionally equipped with:

thermometer;
parameter change indicator;
display the date, time and atmospheric pressure.

The principle of operation of a hygrometer-psychrometer

Psychrometer translated from Greek means “cold measure (measurement). This is the main answer to the question of what the hygrometer measures. In other words, it can be used to measure the temperature and humidity of the air.Its principle of operation is based on changing the physical properties of the liquid. During this process, water evaporates. It loses energy, therefore, the temperature drops. Such a decrease is recorded with a wetted thermometer.

It is important! Before using the psychrometer, you need to know that the evaporated liquid is located next to the psychrometer, therefore, affects its readings.

Its main difference from a hygrometer is in principle of functioning, the operation of which is based on changes in the physical and chemical properties of substances with fluctuations in air humidity.

Psychrometer data are measured using tables

Types of hygrometer designs

A device for measuring humidity must be purchased if there are small children in the house. And even more so if installed conditioners... Manufacturers offer models equipped with various functions. Each of the devices has its own positive and negative properties, which are best known in advance.

Electronic

The room electronic thermometer-hygrometer quickly measures indoor humidity readings. Inside the device, an electrolyte (lithium chloride) is applied to the plate in a thin layer. Voltage passes through it and goes to the display panel.

Electronic device

Mechanical

For measuring humidity in a room, many opt for a mechanical model. It is easy to operate, its price is less than that of an electronic one. However, its readings may have an error. The simplest instruments are not certified and do not pass verification by meteorological services. Therefore, in this case, one cannot talk about the accuracy of the readings.For indoor mechanical hygrometers-thermometers, the place of their installation is important. Most often, wall models are offered, which does not always fit into the interior.

It is important! Mechanical wall models are recommended for stationary use.

Basic rules for choosing a room hygrometer

In order to get the most out of the device, you need to know before choosing how the hygrometer works, what measurements will be made with it, and determine the conditions for its operation. In addition, the external data of the hygrometer play an important role.

Measuring range

The devices can be supplemented with built-in thermometers, with which the air temperature is measured. Before choosing a model, it is important to determine the location of its installation. The purchase of an expensive device with which it is possible to obtain boundary parameters will not always be justified.

Room type	Humidity range,%
Sleeping and children's rooms, living room	20 to 80
Kitchen, attic space, hall, area near the balcony	10 to 90
Bathroom, toilet, swimming pool, sauna	0 to 100

It is important that the selected device is designed for parameters close to the upper limit of the range.For example, the heating temperature is important for a bath. Choose a model that will accept temperatures up to + 120 ° C. This will prolong its functioning.

Error

Measurement accuracy is also important in certain cases. For example, in hospitals, warehouses. The psychrometer shows more accurate humidity data. Deviations of an electronic device can fluctuate within 5 ÷ 10%, condensation - 1 ÷ 5%.

Scale 0.1% for accurate measurement

Moisture determination time

Many substandard products from unknown manufacturers have been released on the market. In the production of such devices, outdated methods and methods for measuring humidity could be used. Therefore, it is important to decide where to buy a room hygrometer, the availability of appropriate certificates for this product at the point of sale, and especially important - guarantees.The device, which displays data after 1 minute, shows information and humidity of a minute ago. For children Are invalid parameters.

You should know this! The optimal level of time for measuring parameters is up to 5 seconds. Professional devices determine humidity in 0.1 seconds.

Electronic devices determine humidity in a short time

Additional functions

The choice of additional functions in the device increases the cost of the hygrometer. Therefore, it is necessary to decide on the appropriateness of such a device for home use in each case separately. Here are the main functions of digital models for acquaintance.

Meteorological stations;
thermometer, clock with built-in alarm clock;
informing about the approach of parameters to the upper or lower limits;
radio nanny;
built-in thermocouple, with which you can measure the temperature of the bed or bottle with baby food.

How to use a hygrometer

The hygrometer is quite easy to operate. The principle of operation is based on monitoring changes in the parameters of dry and wet thermometers. They constantly measure the readings of the environment. The air humidity parameter is calculated based on the temperature difference.

In the simplest hygrometer, the humidity is determined by the table on which the corresponding temperature data are applied;
modern electronic devices independently calculate these parameters, the final values are displayed on the display.

How to make a hygrometer with your own hands

There are several options for making a device with your own hands. We offer you to get acquainted with the simplest way to measure humidity with a napkin. Its principle of action is based on the absorption of moisture by it. The movement of the wire arrow will indicate a change in humidity in the room. You can use a store device to apply a scale of values on a napkin.

We will need: a napkin, a small sheet of plywood, nails, glue and wire.

Photo	Description of work
	Drive 2 nails into a sheet of plywood at a distance equal to the length of the napkin.
	You need to glue a napkin between them.
	Attach 2 pieces of wire up to 4 cm long to the napkin, with 1 part partially attached to the nail, the other partially to the napkin. An arrow should form.
