How to choose the right measuring instrument?
Indoor and outdoor levels
When choosing an appropriate measuring insturment, it is important to determine what you wish to measure. If you are only interested in controlling the humidity in the room, a room hygrometer is sufficient, which usually measures the temperature.
Often, for ventilation it's a good idea to know the situation outside the window. Devices with a wireless sensor are suitable for these purposes. Pay attention to the sufficient range of the signal, the wall and other obstacles between the sensor and the base can interfere with it.
Ventilation warning
Some measuring instruments that monitor the indoor and outdoor temperature and humidity can help you with ventilation. It will warn you that ventilation will help return the internal humidity value to normal.
Indoor memory
If you want to see the values measured by the instrument when you were not looking, the indoor memory function is useful. Most measuring instrument with memory show maximum and minimum measured values since last reset or in the last 24 hours.
Development chart
When measuring values, it is often advisable to monitor not only the current value, but also recent developments. A value development chart, which tells you when the air condition was good and when not, is excellent for this.
What about humidity?
It is important to distinguish between relative and absolute humidity. While absolute humidity directly expresses a specific value for the amount of water vapour in the air (in g / m-3), the relative humidity indicates the ratio between the actual and the maximum amount of water vapour in the air (in%). Relative humidity depends on the air temperature - the higher the temperature, the more water vapour the air it is able to hold.
