Hygrometers??

[Kgbao]

I’ve seen a lot of comments about someone’s hygrometer is good had a bad one etc..

So I wanted to ask in reference to incubators, what model, makes, etc do you use? I’m trying to find one to make a homemade incubator, but the possibilities are limitless and I rather look for some that have been tried and tested to work.

Thanks

Any thoughts?

Weird. I found your post while wondering the same thing. There must already be an answer somewhere on here.

Accurite makes a pretty fair hygrometer/thermometer.
Can't calibrate the thermometer but you can salt test calibrate the hygrometer.
I've gone through quite a few until I have found 4, that are fairly accurate, within 1% difference and have a couple that are 'dead on' every time I calibrate them.

Being a little off isn't too bad...as long as you know how far it is off, you can add or subtract from the reading to get the actual %RH. Plus, they are relatively cheap...~$9 from WalMart.

Thanks. I have a couple of different Accurite digitals, as well as a non-digital Accurite, in my DIY incubator. It's weird how (a) the digitals are so different in their readings; and (b) even if I calibrate the non-digital to read the same as one of the digitals, they will be inconsistent shortly thereafter.

I was not familiar with the salt test calibration method. Having looked it up, I'll have to try that later today or tomorrow before putting some more eggs in lockdown for the rest of the week.

Thanks again.

Try to do the test in a room that has a stable temp. Also, if you have a sealable wide-month jar to use, it will be better than a ziplock baggie.

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.

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.
