Hello, I Need some help... I will be incubating eggs is March. Incubator all set. Tested and retested BUT which thermometer is right? Regarding thermometers: Each seems to register a different degree.. Accu-rite digital thermometer with humidity check: temp shows 97 degrees/35 humidity - will fix humidity once I get an accurate thermometer. Small plastic Springfield red alcohol thermometer shows about: 99-100 Cooking thermometer probe: 100 Purchased a vintage Rexall Clinical Thermometer with mercury on ebay this week: 104 Right now, the readings are..listed above. According to the Clinical thermometer (104 degrees in the air circulating incubator, I would have killed any eggs by going with them.. Is the Clinical thermometer the accurate reading? Help I don't want to kill the hatching eggs I have purchased..soon to be shipped in a few weeks. I will not set any eggs till I have the right thermometer. I keep buying thermometers.. lol to find each one is different... sigh... Thank You!!! Also, How do I calibrate the clinical thermometer?
