The iHealth PT2L thermometer gives a result equivalent to an oral temperature. If you would like to compare the results obtained with your iHealth PT2L thermometer, please compare it to an oral temperature. Ear and rectal temperatures are normally higher than oral and forehead temperatures.
During an episode of fever, it takes time for the heat conduction to reach the forehead. There is a time lag. We recommend measuring the temperature every 5 minutes until the temperature stabilizes.
