I'm with ya there. I used to have 0 hygrometers, I now have 4! None of it still makes since to me. I have 2 digital and 2 analog. of course they are just cheap ones. I calibrated them with the salt per instructions i've found on here. my temps in the room upstairs was 78 degrees over night. I wrote down all the readings for each. The next day I put the same bag in the incubator that was set at 99 degrees with the same salt mixture for 12 hours. none of the readings were the same or close to the same % that they were off from over night in the 78 degree temp. Then I took them out of the bag and just layed them in the incubator with no water in incubator. All were off again the ones that I had to add like 5 was now reading higher then the ones that I had to subtract to get the 75% from the first time.
example: hygrometers
#1analog in bag at 78 degrees 68%, in bag in incubator at 99 degrees 60%, incubator no bag of salt 25%
#2 digital 78% in 78 degrees, 57% in 99 degrees, i.n.salt just read low
#3 digital 70% in 78 degrees, 66% in 99 degrees, ins 16%
#4 analog 69% in 78 degrees, 69% in 99 degrees, lower than 0 in ins
So which one would you go by? I'm not sure!
I think I may be over thinking this. My incubator is the syrofoam hovabator forced air and it's in my basement but it's a little drier than normal here, no rain, no snow and my heat is on although I have the vent closed to the room it's been about 68 degrees in that room and I keep the door closed.
I'm not positive but I think I'm getting obsessed with this humidity thing and it's driving me crazy that I can't figure it out. It seemed so easy when I first read about hygrometers
. Before I got my first batch of "proof of concept" eggs I decided to get a Meade TM005X-M Wireless Indoor/Outdoor Thermo Hygrometer. The bator was warmed, I drove 50 miles to get some fresh fertile eggs and joined the circus. WIth the auto turner I dont have to open the bator at all till I candle on day 10.
