On these unusually cold mornings I would like an accuate temerture reading
outside. Weather Underground web site says 32. My new Accurite wireless
digital indoor/outdoor says 30. My alcohol regular outside says 26. What's
the solution? I'm tempted to rely on the $10 Accurite but probably because
it's the newest and most expensive.
What do you use?
You know it's time to clean the refrigerator
when something closes the door from the inside.
I suspect that with sun and wind, each may
be accurate. The unit in my vehicle reads
two degrees high, if the radio says 32, my
truck will read 34. Of course, you might
want to get a non contact IR thermometer,
point it at some thing in the shade, and
see how that reads.

I have a La Crosse wireless. It closely tracks the reported weather

Can't say I've paid a lot of attention to how accurate they are, but
for temp, I haven't noticed anything unusual, readings seem right.
For humidity, they are not even close. I've had 3 of them side by side,
they are differ by 25 between them. You can calibrate them using a
closed container with damp salt.
I guess if you want to test the accuracy of your temp unit, you could
probably devise a test. I would think if you took a picnic cooler,
filled it 3/4 full with a mix of ice and water, put the thermometer
on top of something floating in there, closed it up, left it alone
for an hour, it should be 32F.
A Davis Vantage and the 60(+?) indoor/outdoor dial both are generally
with a couple degrees at most and the conventional is mounted on the
north porch where it may have some influence from the house...both are
also generally within a degree or so of the local airport readings altho
it's easily possible for there to be a few degrees real in the indicated
owing to local cloud cover, wind variations, elevation, installation,
etc., etc., etc., ...
The other point on using one is valid... :)

I have a fluke dual channel recording temp thermometer. The 2 channels never matched from when it was brand new. Yet it works fine. I use it for work.
But truly what difference do a couple degrees matter? Temp vareies for so many reasons OP has too much time on his hands
I have an outside wireless and see similar "discrepancies" The
difference is location. One is mounted in the shade about 8' of the
ground and 10' from the house. It is generally 1 to 2 degrees higher
than the one in my car closer to the ground.
I also have two weather apps on my phone and they differ a couple of
degrees from each other and from my readings. They evidently us
different sources too, when the town is looked up. There the local radio
station . .
I watch my car thermometer on the 24 mile commute to work. Some days
there is little to no variation, other days it can swing five degrees
along the way depending on wind, altitude, sun load, snow cover and more.
Is the Accurite next to the alcohol? If so, that is a big difference
and I'd probably trust the Accurite.
I've been pricing home weather stations for yrs. Davis always looked
like the clear winner until I found a home weather station forum and
ppl with Davis stations were not so happy. It boiled down to, if yer
gonna get a station that's gonna fail, why spend so much money.
So, apparently, Davis station are not the bullet proof heavy duty
units you are led to believe by the price tag.
Davis has range of product you can choose from.
Mine is just wireless and only thing it needed was
new battery. No problem what so ever. Professional grade
ones are much more expensive. It can feed real time readings to
NOAA grid via Internet too. May be those who are not happy were
who don't know what they are doing. I always see this on other
products. They buy beyond their ability to use it properly and complain,
go out buy another newer one and complain again. At least I know what I
am doing with every thing I own and use. Davis have all the replacement
parts for repair if problem occurs.
While I always recommend Fluke products, I jes looked at the last 3
Fluke meters I purchased. One is from China, one from Taiwan, and the
3rd doesn't say.
China's crappy manufactured products are only as good as the parent
company, which is typically US based. Remember when "Made in Japan"
was a sure sign of junk? Well, as Japan got their act together, many
of Japan's mfr'd products became the gold std. Same will happen to
China. Their products will continue to improve, but only as good as
the parent company. I trust Chinese made Flukes are good meters.
They've proved to be, so far.
Problem is not made in China. On what specs they are made there?
Most every thing is made in China, like Apple product. Even my high end
AV receiver is made there but QC is strict and nothing wrong with it.
Just like old saying "you get what you pay for"

Not just Japan. Add made in Taiwan and Korea to the list. All started
making cheap stuff of dubious quality, but evolved to be world class
manufacturers that kicked our asses in many markets. The younger folks
today don't remember the days when, as you say, made in Japan, was a
reference that meant cheap, inferior stuff. Not any more.
