How accurate is the HUMIDITY reading on these? Please only answer if you've tested/compared it to other devices and/or local weather stations. THANKS

The humidity reading on my old unit that eventually failed got funky and was reading about 30 percent lower than what it should have been. But the replacement unit I bought over a year ago has been right on the money so far. What's weird, however, is that the humidity reading INDOORS on my MAIN unit has gone bonkers now and is reading about 20 percent less than it should be. So go figure. But I have a digit-readout humidifier that I use in the winter, so that's not as important to me as the temperature.

I have had no problems. The set up is simple. Just pick the humidity setting in 5% increments from the top-mounted control panel using the up or down arrow buttons. The lowest setting is 45%.

I would call them "water resistant", not proof. They have a rubber seal inside a groove that protects the battery compartment. That said, I hang them somewhere under an eve, mostly to keep them out of direct sunlight. If the units sit in the sun, you get temperature readings that are too high. As far as rain and heavy weather, I live in the tropical rainforest part of Oregon and I've never had any trouble with the sensors going bad. Getting them to stay connected to the base can be a challenge though. Always use lithium ion batteries, or you'll regret it.

I would recomend it. The one I have works well. Temp is accurate within a deg or two as far as I can tell and the humidity is pretty much spot on.

You can test humidity calibration by making a simple test chamber. In a sealable plastic container, place a tray of common table salt and water (excess salt to make sure it is a "saturated" solution). Place the humidity probe inside the container (do NOT let it set in the solution!), seal it up, and let it set in a constant temperature location for a day. I forget what the exact humidity ought to be, but it's around 70% and you can google it to find what the "exact" number should be. It's the same principle as the cigar hygrometer test kit already mentioned.

It depends on expectations and also how tight your house is and on the water temp. In my case I have the smaller unit for 2250square feet and it does just fine keeping the humidity around 35% in very cold weather actually higher than I should have it based on the windows fogging :)

I use three of them in addition to the humidifier that came with my humidor. I try to obtain 70% humidity..... With that being said, I was given a larger humidor recently. The humidifier that came with it plus the three drymistat humidifiers would only raise the humidity to 62%. So, I ordered yesterday this in hopes it will help raise the humidity..... http://www.amazon.com/gp/product/B000PUWHJC/ref=oh_aui_detailpage_o00_s02?ie=UTF8&psc=1 Good luck!

I have used them outside in S Florida with ultra high humidity. They have been out there close to 6 months with no issues. Hope this helps.

dear God return it if you can!!! I keep mine on 50-55% humidity. Not a temp. but a percentage of humidity. bad designed product, I exchanged mine 3 times in the last 3 years at home depot.....

Humidity is rated not in degrees of any kind, but as a percentage. It is the same all over the world.

Hey. I really wish I could help you but I have no idea on an ACCURATE frequency range. I remember reading some stuff when I bought them, but that was only what the company or Amazon claimed about them. I don't know if there's a way to measure, but I don't have any tools for that kind of thing.

The visible "fog" never filled the entire room... Mine looked about the way you described it, with mist going up a couple feet and then falling. However, the relative humidity in the entire house did go up over time. I know that because the sensor that reads relative humidity was in a different location in the house. If you have good air circulation in your house, things should be fairly constant throughout... But obviously it will be wetter directly in the flow of mist from the unit.

Bought one some time ago, what I found out is the air flow is low volume. Hold your hand over the top and you will feel a slight air flow.I installed a small computer system (thermal logger) and download the data every 6 months to check on the temperature and humidity. My readings are consistant year round. hope this helps

We found out that humidity is everything. On a dry day the output is so-so. On a humid day it is incredible! Regardless, it is a great little machine.

I wish I could give you a decent answer but can't. I installed them above our kitchen sink and thus didn't worry about their resilance to humidity. They do work well though.

Thanks. How do u like it so far. It seems rather expensive if u have to replace a wick every couple of weeks. Would you recommend this humidifie? And thank you for the information.

If the setting dials are working? The air humidity should trigger your fan....if not you may seek a replacement unit....Thank you..11/23/2013
