Buying advice: How to find the right product in our fever thermometer comparison 2022

The most important in a nutshell

  • If the fever thermometer is used for several people, a contactless measurement has clear advantages. However, this measurement method is still unfamiliar to many and it is necessary to keep the right distance.
  • Alternatively, you should disinfect the fever thermometer after each use. This is recommended despite the use of covers, as the handle for measuring is also touched and viruses or bacteria can be transmitted in this way.
  • While earlier fever thermometers contained mercury, today’s battery thermometers are mostly digital. But there are also analog expansion thermometers with more environmentally friendly ingredients than mercury, which represent an alternative for environmentally conscious people.

How does an infrared measurement work?

All objects and organisms with a temperature above 0 Kelvin (around -273 degrees Celsius) have measurable, infrared radiation that we cannot see. A lens bundles the rays onto a sensor, which passes the information on to the electronics for processing.

The range of fever thermometers is confusing for many – especially if you are rarely ill and have not dealt with fever measurements for a long time.

If you had a cold from time to time, a hand on your forehead was often enough before Corona to roughly check whether feverish flu could possibly be behind it. And somewhere in the drawer, there has been a thermometer lying around for a long time, of which it is no longer so clear whether its measurements can still be trusted.

Then you should decide whether a fever thermometer for the ear or one for the forehead is better suited for your purposes. Or maybe a fever thermometer to measure in the mouth? This buying advice will give you the necessary information and some interesting tips.
