Hygrometers??

Awesome. Thanks. I'll do it with a Mason (Bell?) jar and find something I can fit inside with the right mix of salt and water. Looks like about a 2:1 mix per the instructions I found online really quick. But I'll Google around a bit more before actually doing it.

A regular soda bottle cap or a medicine bottle cap will work just fine. Place enough salt into the cap to be level with the top. Drop enough water onto the salt to make it damp, not a slurry. Place in jar along with hygrometer and wait at least 8 hours for it to stabilize before taking a reading, 12 hours is better. HTH

I use and trust IncuTherm hygrometer thermometer, available from Incubator Warehouse.
Here's what they say about it:
The IncuTherm Series has been factory calibrated to be accurate to within +/- 1°F (0.5°C) in the incubation temperature ranges. This is twice as accurate as most standard digital thermometers available on the market. This accuracy level makes the IncuTherm Series the easy choice when selecting a digital thermometer for your next hatch.

Can you provide a link to the model you trust?
