Need a Thermometer for the incubator.

[TenOC]

I have a 35 egg styrofoam incubator. I am getting it ready to hatch a batch of eggs. I also have 3 digital thermometers. The three vary by a few degrees. I read the specification of a number of thermometers on line and most have a variance of plus or minus 2 degrees. That is a swing of 4 degrees. Any suggestions on a good but not $$$$$ thermometer?

As long as you calibrate your thermometer/s against a medical type one so you know how much its 'out' by you should get on just fine.

Here's a great article on the subject:

Depending on the temperature range of your thermometer you could calibrate it using boiling or freezing water.
