Me, too. My combo hygrometer/thermometer from Incubator Warehouse (the one with the probe) consistently reads in the 98 degree range, which is low compared to readings from my other thermometers. Is yours reading low?
The one that came with the incubator (which I was cautioned not to trust overly much) consistently reads about 101.
The best thermometers I have, a digital meat thermometer and a digital candy thermometer, both read about 101.2 or .3, same as the cheapy that came with the incubator. This makes it appear that the digital hygrometer/thermometer is the one that's off.
As luck would have it, my stovetop cracked the other day, and I'm waiting on the part, so I can't even boil water to check those out!!
From what I've read, the range indicated by all these different thermometers is still acceptable, but if the temps are off, the hatch could be delayed or speeded up by a day. But I'd just like to know which one(s) are right.
Is there an optimal place to position the hygrometer/thermometer in the incubator? I'm using a Hovabator Genesis 1588. That's with a fan, digital thermostat and using an egg turner.
