How to maintain the accuracy of your Smart Ear

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:

  1. Clean the ear itself of earwax and other debris. But don't use a cotton swab because this can injure the ear. Follow this guide from the Mayo Clinic to clean the ear safely.

  2. This step is very important - don't skip it. Clean the ear sensor using a cotton swab with alcohol or an alcohol wipe. (see image below) Alcohol helps to remove earwax from the sensor, rather than smearing it across the sensor. If there's anything left on the sensor, it will stop you from getting good readings.

  3. Before taking a reading, choose one ear to use for readings and stick to using that ear. It may sound strange, but there is a small temperature difference between both sides of the head. Choosing just one ear will produce more precise readings.

  4. The Kinsa Smart Ear uses an infrared ray to measure the temperature inside the ear, and so a small or curved ear canal can interfere with the accuracy of a temperature reading. Get the best readings possible by using this technique:
    • For infants under the age of 1, gently tug the ear straight back to straighten the ear canal before taking a reading.

    • For children over the age of 1 and adults, gently tug the ear straight up and back before taking a reading.

  5. If you're still seeing inaccurate readings, the last thing to do is to reset your Kinsa. The reset steps are different depending on whether or not your Kinsa has a side button:
  • If your Kinsa has a side button and a large round button on top, hold down both buttons for about 10 seconds. When you see the Bluetooth symbol flashing on the display, the reset is complete. Wait for your Smart Ear to power off by itself, then turn it back on before taking a new reading. Note: This reset will break the connection with your phone, and you will need to reconnect them again.
  • If your Kinsa has no side button and just one large round button on top, remove the batteries, wait 10 seconds, then put the batteries back in.

The acceptable range of temperatures with the Kinsa Smart Ear is 0.8 F. If you're still seeing a bigger range than this with your readings, please tell our Customer Happiness Team right away at kinsa.help/ContactUs and we'll take care of you!
