- Check that the thermometer lens is perfectly clean. If in doubt, clean the lens with a cotton swab lightly moistened with isopropyl alcohol. After cleaning, wait 30 minutes before taking a measurement.
- Check that there is no hair, sweat, cream or other cosmetic products on the forehead surface.
- Make sure that the thermometer has been at the ambient temperature for at least 30 minutes.
Please note that different measuring sites could result in different measurements.
- The average normal oral temperature is 37°C.
- A rectal temperature is 0.3°C to 0.6°C higher than an oral temperature.
- Ear (eardrum) temperature is 0.3°C to 0.6°C higher than oral temperature.
- Axillary temperature is generally 0.3°C to 0.6°C lower than oral temperature.

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.
