Little Giant's Circulated Air Incubator sets the standard for incubating and hatching eggs, with updated digital technology. The built-in fan constantly circulates the air to maintain a proper temperature throughout the incubator, eliminating harmful hot and cold spots while the durable Styrofoam retains warmth, generated by a gentle heating element. The LCD display with LED light shows accurate temperature and humidity readings instantly and the self-regulating control board adjusts the temperature to suit varying environments. The built-in digital hydrometer and moisture channels help maintain humidity, a key factor in egg health. Plastic mesh screen safely supports eggs during hatch period and is also dishwasher safe. Two 4 inch by 8 inch viewing windows allow for monitoring the hatching process and are great for educational purposes.
