Good luck!
And please don't take this as a smart-*** comment, but just because 2 thermometers are close to each other, doesn't mean they are accurate. Do the ice test on them, if they can read down to 32°
agreed and I find you can't trust most thermometers. someone posted fish tank thermometers which are very accurate but hard to read $3 at walmart . I have spent a lot of money on thermometers trying to find one that works right . about 1 out of 4 is close to right. I like thermometers and hygrometers that can be set after I calibrate them. the one I like the most is a mainstays probe type quick response cost $9 at walmat .it's used for cooking and calibration instructions on the the card. it fits in the small vent holes in my farm innovators so I can check the temp. at all 4 corners of the incubator. not that I can change them at all . My hygrometers are hygroset IIs for humidors they to can be set after calibration and are very accurate . I brought 3 only 1 had to be reset after calibration .They are $20 on ebay but you can't trust the thermometers on them.
