I would say this thermometer, if not accurate then its almost accurate each time. Really easy to read, easy to use. Great thermometer and so much easier to use than the traditional thermometers. Love it!

This Zewa 4-way rotating infrared thermometer, has really made things much easier, and hygienic. My 9 month old son, isn’t crazy about the method I’ve used up until now. Trying to hold the thermometer in place in his armpit, while he’s squirming about and trying to roll over, doesn’t do the job as well as I think it should, so having this no touch thermometer, which I can just point at his forehead, is, not only easier, but more accurate as well.This thermometer can be used accurately, by using a built in distance detection feature. With its rotating head, you to get a measurement from any angle. There’s no need for physical contact to achieve the reading. With the infrared technology, a reading will appear in 1 second.It has a LCD display, that lights up in one of 3 different colors, depending on the temperature it measures. In addition, the thermometer can store and recall reading up to the last 30 times. I’m especially fond of that, as when my babies ilI, and crying hysterically, I can immediately comfort him after I take his temperature, without the need to keep a physical log of the readings.This thermometer is more than one you can use to take a persons temperature. It can be switched, from a persons temperature, to an object mode and give an accurate reading of stable objects. I actually use that feature, when I’m drawing a bath for him. As most of you know, there’s no need to read a thermometer for that, as most people can tell by touch what the water temperature is safe or not. But, because this is our first baby, my husband was always hesitant to put our son in the bath water, without knowing its temperature.The power source for this thermometer is 2 AAA batteries which are included. There’s also no need to worry about running the batteries dead by accidentally leaving it on, as the thermometer has an auto off feature.I really like this thermometer. It’s been very easy to use, and I highly recommend it.

Works easily, just tilt the sensor towards you to turn on and take your own temp, or away from you to take another's temp, or straight up if that works better. Then tilt the sensor back down to turn off. While off (sensor turned down), hold in the side button until you hear a beep, then you can set C° vs F°, and the date and time. The screen quickly indicates good, caution, or fever (green, yellow, red). The instructions say it can remember up to 30 readings, but I didn't explore that. It appears to be accurate, though I'm sure an under-the-tongue type would be a little more accurate. But even if it's within one degree, that should be accurate enough. Easier than an oral thermometer, and certainly easier for use with kids.It takes two AAA cells, which is my preference. Thermometers go for long periods of non use and use very little power when they are used, so replaceable alkaline cells are perfect for such situations. Good alkaline cells generally last about 10 years (I have some still going strong after 20 years). Some people might prefer a built in rechargeable battery, but that's less desirable for this particular use, would increase the cost unnecessarily, and would be less likely to be ready to go after a long period of non use.4.5/5.0

I feel so medical. This is a cool looking thing, whether or not it works, and it does happen to work. It is simple to operate and does not have to touch my scalp to get an accurate reading. It makes a tiny beep when complete, normally taking just a couple of seconds to get my temperature.The only problem, and it isn’t very bad, is that the screen does not block out the background very well. The actual temperature reading has some clutter behind it, but is still easy enough to read.

Thermometers can be designed for taking oral, rectal, ear or forehead measurements. The Medical community believes that both oral and rectal thermometers give the most accurate body temperature readings, however, neither method is very efficient for checking large groups of people and they are both certainly more difficult to keep sanitary as you move from person to person. Forehead thermometers (FT) use Non-Contact Infrared sensors to measure the temperature of blood vessels just below the skin’s surface – in this case the ones associated with the temporal artery, which run across your temples and forehead. Ease-of-use makes these FT devices popular, despite the somewhat lower accuracy.The distance of the FT’s sensor from the surface of the forehead can have a large impact on measurement accuracy; this device from Zewa includes a built-in distance measurement to make sure you are not too far away. It will warn you by displaying the word “FAR” rather than the temperature (see photo) if you exceed the expected 2” measuring distance. The specific emissivity factor used will also have a direct impact on a FT’s accuracy. A lot of industrial infrared “thermal cameras” use a default emissivity of 0.95, while the accepted emissivity value for human skin is 0.98; this is why thermal cameras aren’t a good substitute for true FT’s. I checked the product documentation for this thermometer and wasn’t able to find any information re: the emissivity factor used.When placed at the right distance, the measurements from this Zewa thermometer are extremely quick (~ 1 second). The Owner’s Manual indicates a measuring range of 93.2F – 109.4F; outside this range the display will indicate Lo or Hi, respectively. I measured myself (indoors, out of direct sunlight, at-rest and healthy) and I got a reading of 97.1F, along with a Green display color. I repeated the measurement 4 more times and always got 97.1F, which is surprisingly consistent. The display is Green for measurements less than 99.1F; Yellow for 99.2-100.0F; and Red for greater than 100.0F. The Owners Manual doesn’t specify a “normal” temperature range but one can infer from these color-display limits that the manufacturer believes that values of 99.2F and higher indicates an elevated body temperature / possible fever.Normal body temperature is generally agreed to be 98.6F with a range from 97-99F. By that standard, my result of 97.1F was low but normal. My suggestion would be to take some measurements with this thermometer ahead of time, when you know you (and your kids) are well, and then write those “normal” values down on the Owner’s Manual for future reference.One last comment: The included “Qualified Certificate” indicates that the device was made and calibrated in July of 2023. It also lists an “Expiry Date” of July 2026. The Owners Manual indicates that the “Expected service life” of the product is 3 years and the warranty is for 2 years. As I received this in the Spring of 2025, I’m not certain if this means that the calibration is becoming invalid or if the product is reaching the end of its useful life.
