We developed and tested our thermometers for maximum accuracy around typical human body temperatures ranges:
- Between 95 °F and 107.6 °F
- Between 35 °C and 42 °C
If you suspect inaccurate readings from your Smart Ear, follow these steps:
- Check that your ear is clear of excessive earwax and debris. Do not use a cotton swab as this can damage your ear. For tips on how to best clean the ear safely, follow this guide.
- Don't skip this step. Make sure the Smart Ear's sensor window is clean. Use a cotton swab with alcohol or an alcohol wipe and gently clean the round sensor window at the tip of the Smart Ear. Be sure to clean the inner flat surface of the sensor, not just the rim. (see photo below) Debris clogging the sensor is the most common cause of accuracy issues.
- The Kinsa Smart Ear is cleared for use with adults and children of all ages, but ear canal sizes, especially in newborns, vary significantly from person to person which can affect accuracy. To ensure the most accurate reading possible, please use the proper technique:
- For infants under the age of 1, gently tug the ear straight back to straighten the ear canal before taking a reading.
- For adults and children over the age of 1, gently tug the ear straight and up and back before taking the reading.
- Remove the batteries for one minute and then reinsert them. This will allow the Smart Ear’s internal components to reset which can fix accuracy issues.
- Lastly, perform a factory reset your Smart Ear by holding down the large power button and the small button on the left side for about ten seconds. Let it power all the way off before you pair and take a new reading.
