I'm hoping someone can help me! I bought a used Brinsea Mini Advance and will be using it to hatch eggs in about 2 weeks. (This is my first time hatching eggs.) I've disinfected the incubator and had it running 24 hours. The incubator says the temp is 99.5 degrees. However, my Spot Check thermometer (which is supposed to be really accurate) reads between 100.9 and 101.0. My digital candy thermometer reads 101.8. Based on these readings, I think it's about 1.5 degrees warmer in the incubator than the Mini Advance is indicating. This is a BIG temperature difference! I don't want to cook the eggs! (OK - yes - I'm panicking) When I turned on the incubator, I held down the OK button while powering the unit on to bring the unit back to the factory settings, but this did not correct the problem. What do I do now??? Which thermometer do I trust?
