The mechanical Hygrometer-is an instrument used to measure humidity. Since this indicator is very important in human life, hygrometers found wide application in the home and in industry. There are many varieties of the models of the device. The Modern market offers these devices, combining them with other instruments, in particular thermometers or clocks.
Classification of hygrometers
Instruments for measuring humidity are divided according to the principle of into three groups: mechanical, electrical, and condensation.
The mechanical Hygrometer can be hair, film, weight.
The Principle of operation of the hair appliance based on the properties of the length changes of fat-free hair depending on the humidity of the environment. In a special frame to stretch the hair, which is connected with an arrow, responsive to the change in its length. Readings are displayed on a scale.
Such devices use in meteorological stations, they are quite accurate and reliable.
Film hygrometer is based on the mechanical properties of the film reacting to the increase and decrease of humidity. This changes the surface area of the film. The arrow reacts to changes in the position of film center, which is displayed on the scale.
In the weight hygrometer hygroscopic substance is used, filling of the tube system, designed in U-shape.
Condensation hygrometers based on establishing the dew point, which is determined by the temperature of a metal mirror during cooling, at the moment of appearance of condensation on its surface.

Hygrometer
Industry produces hygrometers depending on the scope of application: industrial and domestic. Electronic models are the most popular. Usually they are provided with a thermometer and called “the hygrometer-thermometer». This is useful because it displays the indicators of humidity and air temperature. Devices with external electrodes are universal.
The importance of measuring the humidity of the air
Scientists have shown that low humidity combined with high temperature adversely affects the human body, compromising its functional performance and weakened immunity. Optimal humidity for humans is considered its value is above 40%.
Hygrometer mechanical, psychometric and other widely used in medicine and in everyday life.
Modern psychometric instrument is designed for studies of the readings of relative humidity and air temperature in different rooms for the storage of materials, poultry farms, silk farms and warehouses. The devices are available in various versions and different temperature range and moisture characteristics depending on the application.
The psychometric Hygrometer made in such a way that a temperature gauge and two thermometers fixed on the basis of plastics, and research is conducted accordingly psychometric table. The thermometric liquid is that the device is toluene or mercury.
