Review on 🌡️ Digital Alarm Thermometer for Aquarium, Fish Tank with Hygrometer for Room, Reptile Tank, Egg Incubator - Mini Alarm Indoor Thermometer with Magnetic Stand by William Runninger

I used it along with two others (different brands) for an egg incubator and installed it in the incubator. This one and one of the others measured about 5 degrees less than the other 2. I had a successful deduction by basically ignoring the temperature on this unit. It doesn't seem very accurate and there's no way to calibrate it. Interestingly, towards the end after opening the incubator to take out the egg turner, which affected the humidity, it began to show much closer to other thermometers.
