Review on ETHMEAS Reptile Terrarium Digital Thermometer and Hygrometer - Indoor Outdoor Temperature Gauge and Humidity Monitor for Pet Keeping by Justin Fletcher

I need to check the temperature of the incubator. It's pretty close. I have 2 of them and they are a power apart so I'm just averaging them for my crappy incubator temp. . For eggs, the rate of hatching is directly related to temperature, so if it deviates by half a degree, hatching will stop. You will not get a good hatch rate if you incubate below 99.5-100.5 F°. Moisture is fine as long as it's around. If you need 45-65%, a few % up or down won't make much of a difference as long as you alternate between the top % and the bottom %. eggs. I hate how expensive they've gotten. I bought them 3 years ago and for 2 they cost $7.
