The device is so simple that it normally does not need instructions: D. After switching just press to start the measurement again briefly on the switch and the measurement is completed within one second. A smiley face on the display shows when the temperature is below 38 degrees Celsius and thus there is no fever. The measurement on the forehead between the eyebrows I find easiest. When compared to measurement with an infrared thermometer at the same temperature is displayed and with 0.1 to 0.2 degrees Celsius difference.
If you want to have to measure in the ear to remove the cap and align the sensor body to the eardrum. I find more difficult than the measurement on the forehead. Of course, you should make sure that the thermometer is not polluted by the use. The cleaning with a simple cloth or I like to use more wipes for face cleaning should be sufficient.
The Reer 98020 SkinTemp fast and very very simple measurement of body temperature is possible. The accuracy of fit, the operation is simple, the display is large enough. With the filling of a battery should be long and often able to measure if it is necessary. From my side I am fully convinced. In addition, the price is more than fair.
