TFA 45.2042.50CZ – derinys (termometras / drėgmės matuoklis) 120 mm

This combination hygrometer and thermometer is ideal for living or working spaces, as it distinguishes between ideal climate and conditions that are not suitable for human health. The TFA45.2042.50CZ indoor thermometer and hygrometer is equipped with a folding stand to stand on, so it can also be hung on the wall, and unlike competing devices on the market, it has labels completely in English.


Relative humidity is the ratio between the instantaneous amount of water vapour in the air and the amount of vapour that the air at the same pressure and temperature would have at full saturation.Relative humidity is given in percent (%). Relative humidity is also sometimes referred to as relative humidity.

Note: The main limiting factor in calculating relative humidity is the temperature of the air, since for a given temperature the air can only hold a limited amount of water vapor. The higher the temperature, the more water vapour the air can hold. In practice, therefore, if the air temperature drops while the absolute humidity remains unchanged, the relative humidity increases and vice versa. Temperature and humidity have a great influence on psychological well-being. Therefore, special attention should be paid to these two parameters, especially in living and working areas.

The artificial hair hygrometer is a very accurate instrument. Compared to a spiral hygrometer, which only indicates correctly within a certain range of the scale, a hair hygrometer can be adjusted to show the correct value over the entire scale range.
