Smart thermometers: the non-invasive way to measure temperature

Only available in hospitals to measure the temperatures of patients without touching them, smart thermometers have been brought to our homes by companies such as Koogeek and Withings. Unlike traditional methods, this is a much more sanitary way to take anyone’s temperature.

The technology is relatively new and infers temperature from a portion of the thermal radiation emitted by the object being measured. These trackers are sometimes referred to as laser thermometers, as a laser is used to help aim the thermometer.

Withings Thermo

View technical specs

Withings Thermo, perhaps the best known name on this list, is the first smart thermometer to be approved by the US Food & Drug Administration. A fast, simple, no-contact gesture yields a temperature reading, and automatic sync with the dedicated app also allows you to track your stats, get reminders, and input related symptoms/medications right on your smartphone.

thermo-application-c Thermo has 16 sensors which take over 4,000 measurements to find the hottest spot on the side of your head. The device measures from the temporal artery, considered the best place to detect temperature changes as the blood that circulates there comes from the core of the body. And since there is no contact with earwax, saliva or any other body fluid, this is an extremely sanitary way to take anyone’s temperature.

Thermo delivers color-coded feedback on the device that is relevant to the user’s age profile, to help you understand the reading. For more advanced info and health advice, head over to the app.

Up to five family members can have profiles within the app. In addition to tracking temperature and symptoms, you can enter comments, and medications in any user profile. This helps you see if the treatment is effective and allows you to maintain a log to share with a doctor.

51x3fp244cl-_sl1001_Koogeek is a relatively new entrant in market for health and fitness technology.

The Koogeek smart thermometer is extremely easy to use. A quick look at the instructions is all that it takes to be able to use all of its functions. There are only two buttons, a display, and two indicator lights for in-ear or forehead use.

A simple one second scan across the forehead is required to take a reading. The Chinese company says the measurement error is within ±0.2℃. If you prefer, you can also opt for the in-ear measurement option. This is useful as it gives you the ability to double-check your forehead reading.

The thermometer is dust proof, drop proof and dirt proof. In terms of battery life, this is one less smart gadget you will need to recharge as it comes with a long lasting replaceable coin cell battery.
