If you are looking to gain better understanding of your hatch results this is the tool that you need. You activate it by plugging it into your computer. Then you place it in the incubator and it will record the temperature and humidity at the intervals that you set. When you would like to see what the recordings have been you simply plug it into your computer and it will graph out your temperature and humidity. This will allow you to see why those birds didn't hatch or if your incubator is holding it's temperature and humidity the way you think it should.
This product does not display the temperature and humidity only recording it for future analysis.
