    I need a good hygrometer for my incubator. I was wondering what everyone one thinks is the best. I know there is a lot of junk out there.

    To calibrate (check accuracy) your hygrometer you do a salt test.

    Fill a bottle cap, I like wide mouth or milk jug caps, with salt. Dampen it to a paste/ wet sand consistency. Drops of water, doesn't take much. Put the cap and hygrometer in a zip lock bag. Wait at least 4 hours, up to 8 hours is best. The true humidity in that sealed bag should read 75%. Any deviation to that is how far off your hygrometer is.

    I did this last night and the humidity read 45%. I would say its way off. :). I'm sending it back. Does it matter if its table salt vs kosher? I wouldn't think so but thought it would ask.

    whatever you do DONT buy the cheap one from walmart. I did because it was recommended, and it sucks. WAY off. and apparently you cant calibrate it. waste of money. JMO though.

    I got a $30.00 one the other day, a "WEATHER STATION" and when I put it in the bag with the bag with the salt water, it would only get to 50%. This si the 3 or 4 th one that I have tried this with and 50% is the highest I could get. What am I doing wrong?

    I browsed cigar, reptile, guitar, and "herb" growing forums as they are all big into humidity and hygrometers. The caliber three kept coming up in recommendations. I am using that, and a cheapo walmart one (from what I hear, even though it is accurate now, it will crash and burn pretty quickly). They both match each other, seem accurate, and the temps match my mercury thermometer, so I'm happy.
    Some notes on the caliber III.
    1. Do NOT use the salt calibratin method with this device.
    2. It will appear to be broken at first. It takes a few hours out of the box to stabilize.
    3. It must be in a certain upright position, and the back can't be blocked or it will read waaaay too low for temp and humidity. I have mine propped up and it works great!
