Hygrometer

A hygrometer is a measuring device for air humidity and displays the relative humidity in percent. To do this, it measures the ratio of the amount of water vapour in the air in relation to the maximum that the air can absorb – depending on the current room temperature. The hygrometer indicates whether the room climate is too humid, too dry or optimal. Find the right hygrometer for you now and always keep an eye on the relative humidity.

The world of humidity measurement

Do you want to know more? Or do you want to find out more about why measuring humidity is crucial for maintaining an optimum indoor climate?

On our information page about measuring humidity, we explain why it is important to measure relative humidity, what an ideal humidity value is and the consequences of values that are too high or too low. You will also find out what you can do if the values are too high or too low.

Hygrometer types

Analoge Hygrometer

Analoge Hygrometer nutzen natürliche Materialien wie Haare oder Metallspiralen, die sich je nach Feuchtigkeit ausdehnen oder zusammenziehen. Diese physikalischen Veränderungen bewegen eine Nadel auf einem Ziffernblatt, welche die aktuelle Luftfeuchtigkeit anzeigt.

Advantages

  • Easy to use: They do not require batteries and are easy to operate.
  • Robustness: Thanks to their simple mechanics, they are less susceptible to damage from falls or knocks.
  • Classic design: The classic dial design can look decorative and stylish.

Disadvantages

  • Accuracy: Analogue hygrometers tend to be less accurate, with deviations of plus minus 5 % relative humidity or more.
  • Readability: The needle and dial require precise interpretation, which is less user-friendly.
  • Calibration: Analogue hygrometers must be calibrated manually on a regular basis to ensure accurate readings.

Digitale Hygrometer

Digitale Hygrometer verwenden elektronische Sensoren und Mikroprozessoren zur präzisen Messung der Luftfeuchtigkeit. Die Messergebnisse werden auf einem digitalen Display angezeigt.

Advantages

  • High precision: Digital hygrometers provide accurate readings with an accuracy of plus minus 1 % to 3 % relative humidity.
  • Legibility: The digital displays are easy to read and often backlit.
  • Fast response time: They update and react quickly to changes in humidity.

Disadvantages

  • Dependence on batteries: Digital hygrometers require batteries, which means additional effort for replacement.
  • Cost: They are generally more expensive than analogue hygrometers, although there are also affordable models.
  • Sensitivity: Electronic components can be more susceptible to damage from extreme conditions.

Correct positioning of the hygrometer

Unsuitable positioning can negatively affect the measurement of the hygrometer. It is important that air can circulate around the measuring device and that it is not placed in direct sunlight or near a heating/ventilation system. It is best to place the hygrometer on a chest of drawers or a table. You should not place it hidden on a shelf or directly next to windows and doors.
