iHealth PT3 Infrared No-Touch Forehead Thermometer REVIEW


The iHealth PT3 Thermometer is an infrared thermometer that provides 1-second testing for current body temperature reading. It features a high-precision, ultra-sensitive infrared sensor that measures IR energy emitted from a person’s forehead. It collects more than 100 data points per second. It’s a safe, hygienic way to capture someone’s temperature with its no-touch design. There is a gentle vibration alert that happens when a reading has been completed, which replaces annoying beeps that usually accompany temperature readings. It has an LED-backlit display that is easily readable at night or in the dark. The PT3 also has a built-in distance sensor and environmental sensor to help avoid invalid measurements.

The iHealth PT3 comes in a pretty standard box. There is an image of the product on the front with the name and basic description printed above it. I’m rather fond of iHealth’s brand colors — orange and white — because it makes it easy to spot their products on a shelf. It’s also very clean and matches with a perception of high technology (in my opinion). I really like that most of the main details are shown on the box. One of my favorite features of this thermometer is that it does ‘not’ work with an app. I know that a lot of people would prefer that functionality, but for something like this, I just want a quick, easy to read device and the PT3 does that for me. I’ve used some of those other models that pair with an app and as nice as they are for documenting a fever/symptoms progression through an illness, sometimes you don’t want to wait on a phone to go through its processes. When you have a sick child that just wants to rest, the last thing you want to do is say, “Hang on a second, honey. The app is connecting.” That’s why I like the iHealth PT3. It provides a quick accurate temperature reading without disturbing the patient.

The iHealth PT3 Infrared No-Touch Forehead Thermometer quickly became my favorite thermometer option available. It’s inexpensive and gives you a near stealth way to take someone’s temperature. It’s ideal for those who are very ill — young or old — so you don’t disturb them while they are resting. There are lots of newer technologies that are helping people and many different opportunities to track health data through apps, but the iHealth thermometer keeps things simple by just providing a clear, digital number on its LED screen. I can recommend this for any type of user.
