I just bought an LG Dehumidifier and the "present%" readout
reads about 6 to 10% higher than a digital gauge that I have.
I am certain that the digital gauge is accurate.
The dehumidifier seems to work real well, but I have to set it
to about 55% to get the actual humidity in my basement to
be between 45 & 50%.
Should I swap the unit for another or is this not a big deal?
You pay over $200 and you would expect it to have and accurate
Thanks for anyone's input
Without calibration against a standard, there is no way to know if either
reading is accurate. A digital gauge can be just as inaccurate as an analog
one, it is just easier to read. Humidity generally varies quite a bit with
time and location and measurement is not generally highly accurate. I
suspect both gauges are accurate enough for the intended purpose. If you
want something more accurate get a "sling psychrometer". Just adjust the
humidistat to get whatever you are happy with, either on its dial, on your
digital gage, or because it feels okay and your tools don't rust.

the humidifier has a digital readout also. the other is a small
one I got from radio shack. weather.com said the present humidity was
55% outside. I brought the radio shack gauge outside and sure enogh,
it read 55%
went right to it. so I am assuming that the radio shack gauge is
the dehumifier does suck up moisture real well, fills the bucket (65
every 24 hours. so I guess the reading is not real important.

Really! How approrpriate. Didn't see this until just before posting!
Yeah but does weather.com have a station right outside your house?
I agree with Don too.
If it were something smaller, like a thermmoter, or even your RS
hygrometer, and it doesn't have to be plugged in or a battery
inserted, I look at 3 or 5 or 10 for sale and pick one that reads in
the middle of all the others. If they were all spread out, I gues I'd
buy one in the middle or maybe go find a different brand, but so far,
the only things I've bought. all of them read close together.

I was looking for humidistats, I bought a 4" metal Taylor that stated
to calibrate every 6 months by putting a damp rag around it and
adjusting it to 93%, I then took it to HD etc and all the other Taylor
unadjustables were off by 10-15%. Digital are usualy more accurate but
none are 100% unless calibrated.
I have possible bad news. I believe the highly repudiated junky Kenmore
dehumidfiers were made by LG. They last 1 year. These are the 70 pint
models that give everyone problems. I would consider a whirlpool instead.
