Local Wal-Mart is selling a no contact temp sensor for $10. Be great for checking wheel bearings and other hot spots. Left overs from the COVID selling build up.

I would probably leave them at walmart.
If they are covid ir scanners I would not trust them. I have had my head, arms, ect scanned all sorts of times this past year and they seemed never to be even remotely close to 98.6.
I know our company bought like a batch of 100 when covid 1st started and that batch all ended up in the trash. The replacements did not seem
Much better. The sheet people filled out looked like a random number generator.

I agree with Jon, the Red Chinese are flooding our country with crap and
getting wealthy..
My Stainless Steel Biohazard cart tire blew apart after one year,
Replacement is available only RED Chinese made from Grangers.
I can see why the Chinese ar being picked on.
Yes I am Japanese and look just like them.
One GMC supplier had rear air bags made in RED China, they supplied with
two plis, noet 3 like the original and we had few burst..
Miguel Mendeze of MGM GMC can varify as he was here and saw the blown bag.

Only way to really tell about those non-contact IR thermometers is to
immediately compare with an under the tongue thermometer. As you get
older, your normal body temp gets lower. I don't know what my actual
body temp is, because none of our oral thermometers are working, and I'm
too cheap to buy a new one. All the IR thermometers I've been checked
with read 97.4 or 97.5. Whatever the nurse at the doc's office uses
gives a "reading" of "that's OK".

The better quality IR thermometers normally have a calibration procedure that is required each time you change the type of surface you measure. IR reflects differently dépendant on the surface. Human skin contains moisture that evaporates, thus affecting accuracy.
A machined metal surface reflects more than a cast surface. Density and colour of the surface also has an effect.
The cheap IR thermometers can only give you an approximation. Even the the good ones will be inaccurate on certain surfaces due to all the possible variables.
They are still convenient for identifying extremes, but if you are looking to be precise within +/-2° they are not the most reliable.

I've used IR thermometers for years and no, they never read body temperature as 98. They also don't like some reflective or shiny surfaces, there are reflectivity adjustment factors.
But, for seeing if a wheel bearing is getting hot, surface tire temperatures, finding which cylinder isn't firing, which cooling valve isn't opening, etc., they are great, but get a good one. I have a Cole Parmer
Even better is a FLIR device, then you can find bad electrical connections, overheating motors, hot bearings, etc.

I love my FLIR. It plugs into my phone and I can take videos and pictures in infrared, sometimes even inside of a wall. Great for finding hotspots, leaks etc.

Forward Looking InfraRed camera. I had to look it up. But wow! I gotta
save up for that gadget! :-)

We had a FLIR in the B-52 in the mid 70's. Interesting flying low level at
night.

The average body temperature is no longer considered to be 98.6.
The 98.6 F standard dates to the mid-1800s. German doctor Carl Wunderlich measured the armpit temperatures of about 25,000 people and came up with an average of 98.6 F.
Newer research suggests that the number has since gone down. In a recent review, scientists looked at temperature records from three periods between 1860 and 2017. The average oral temperature slowly fell by about 1 degree to 97.5 F. A person’s age, gender, or weight didn’t make a difference, nor did the time of day.
Doctors have several ideas about why body temperatures are falling. They include:
Lower metabolic rates. Your body uses energy so all your systems can work the way they should. This creates heat. But people may have lower metabolic rates now because we weigh more than people did centuries ago. The less heat your body makes, the lower your temperature.
Lower rates of infection. In the 19th century, infections such as tuberculosis , syphilis , and long-term gum disease were more common. As a result, many people had higher body temperatures.
Better thermometers. We may have more accurate thermometers than people did a century ago.

Maybe i was too general. I have a couple
Ir temp guns at home, and use them on the gmc, my deep frying, the reptile cage. Seem to work fine and you can get an idea if you have a temp by shooting it at your skin.
The covid era ones, like the one at our front desk office, and the other one that comes
To mind was at the front desk at the nursing home my wife’s grandma was at.
The one at our front desk seems to vary about 15 degrees. I just looked at the sheet. Some people coming in with forehead temps or 82. Some at 89. Others at
96.
I have experienced this constantly over the last year(my work has me visiting many businesses to make sure their internet works). I have walked through the same door and been scanned different times and had massive swings.
I had one of my employees sent home for
Too high of temp(normally in covid that secret # is 100.3). Checked him a few times and he went home worried until his home under
The tongue thermometer assured him their ir one was junk. (Wintertime
In MN too)!
Just saying. My experience is to spend a few more bucks on an IR temp gun the. Walmart
Clearance, or you might not sleep
At night wondering if your front bearings are burning up due to an erratic ir reading.

I investigated this several years ago after realizing the every time I or my doctor checked my temperature by different methods I was always 97.5 to 97.9. I never was 98.anything or higher. After investigating this, what I found was 97.7 is average for most people in the US.
