LG Dehumidifier "present%" reads high

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 reading. 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.

LG Dehumidifier and the "present%" readout

Thanks, 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 accurate. the dehumifier does suck up moisture real well, fills the bucket (65 pints) every 24 hours. so I guess the reading is not real important. thanks again

Hi, How do you think digital one is more accurate. Sensing part is still analog. Ever heard of ADC, DAC? Calibrate against known reference.

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.

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.
