Humidity Meters

[Gilligans Island]

Who makes a quality unit that is accurate. I have 4 digital meters and they all read different with a range of 11%. WTF yeah I know what do you expect for $20.00. I would think the one on my dehumidifier might be close but no idea. I would prefer a gauge and not digital although the highs and lows are nice to know as my area is small. What are you using and do you trust it? Thank you in advance for your time.

I have 2 digital meters in my grow area. One says 23% humidity and the newer Chinese meter says 49% haha. The funny thing is they both show identical temperatures. I'm going to order an analog meter just for the sake of it to see what it reads.

Mine too I have two identical and both read within .5 degrees F but are 6% off on humidity. Maybe normally not a big deal but in 225 cubic feet it is.
