Measure temperature with the air-Q icon

Air temperature (T)

The air temperature has a significant influence on the reaction time of chemical processes and thus on the metabolic process of humans.It therefore makes sense to measure it. Temperatures that are too high or too low can have a negative impact on mental or physical health.

Can be measured with:

✓ Measurable with air-Q light, air-Q basic and air-Q pro as well as air-Q science


For humans, the perceived temperature plays a major role. This perceived ambient temperature, the room temperature, can deviate from the air temperature that an air thermometer would measure. The room temperature refers to the temperature that can be measured in a room and is made up of the local air temperature and the radiation temperatures of the individual surfaces.

Limit values for temperature:

For well-being and thus for the prevention of health problems, the Federal Environment Agency recommends specific guideline values for room temperature. A distinction is made between the respective purposes for which the rooms are used.

In the living area, 21 to 23 °C is recommended. For children's rooms and bathrooms, the guideline value is 23 °C, in the kitchen 18 to 19 °C and in the bedroom 16 to 18 °C.

For offices, a room temperature between 21 and 22 °C is recommended. The Workplace Directive (ASR) differentiates between different activities when it comes to the legal recommendation of the room temperature. The minimum temperature for seated and light physical work is 20 °C and for medium physical exertion 19 °C. Medium physical work while standing requires a room temperature of at least 17 °C, and for heavy physical work while standing, the temperature must not fall below 12 °C. The maximum temperature in work rooms is 26 °C.

Consequences of temperatures that are too high or too low:

The individual feeling of well-being in closed rooms depends to a large extent on the temperature and humidity. The decisive factor here is the body's own thermoregulation, which is activated against overheating when the air temperature is too high and tries to raise the body temperature when the temperature is too low, e.g. by shivering. Since thermoregulation is linked to the blood circulation, people with circulatory problems can react very strongly to temperature fluctuations.

In addition to physical effects, an uncomfortable air temperature can also have a negative impact on mental health and limit overall performance.

Too high a temperature can lead to dehydration of the mucous membranes and thus increase the risk of colds. In addition, fatigue and headaches may occur. Freezing at too low temperatures leads to a feeling of sickness. In both cases, concentration and performance are reduced.

At a temperature between 23 and 28 °C, mental performance also suffers, e.g. during office work. The common theory is that this temperature is perceived as too pleasant and too much relaxation sets in. Even higher temperatures lead to an increase in performance due to their unpleasant feeling. One works most effectively when the temperature is perceived as "slightly cool".

Adhering to the recommended guideline values can also reduce energy consumption and thus save resources and reduce emissions. In addition, the formation of mould can be counteracted.

Background of the perceived temperature:

The perceived room temperature results from various factors. Even before the air temperature, the temperature of the wall surface of the room is significant. This is because the four walls radiate heat - and this temperature is taken into account in addition to the local air temperature when measuring the room temperature.

The own body temperature of the people in the room and thus the heat transfer between the organism and the environment also influence the perceived temperature.

In addition, the individual characteristics of the skin, evaporation via the skin and respiration and the air humidity play a role in the perception of temperature. An additional influence comes with solar radiation and thus also with the absorption or reflection properties of the respective garments.

Sensor used:

The temperature is measured in the air-Q by a sensor with very high accuracy. Unfortunately, the air-Q itself heats up somewhat. This self-heating is corrected by mathematical formulas, but the air-Q still reacts somewhat more sluggishly to changes in temperature than an absolutely exposed temperature sensor.

Measure air temperature:

If you want to measure the air temperature and analyse the indoor air as a whole, then buy the air-Q measuring device for healthy living and working.
