Fully automatic largecapacity incubator with selectable capacities: 56, 64, 98, 120, 128, 152, 176, 192, 232, 256, 300, 392. One unit has three uses: from hatching to shelling, the whole process is automated. Humidity and temperature control: The incubator automatically adds water to adjust humidity. The LED display lets you set the target temperature and humidity, and it can determine when to add water based on the humidity readings. If water is needed, you add it from outside the incubator using your own water bottle. Dual power supply: Supports 110V or 220V mains power. After a power failure, it can be manually switched to 12V battery power (battery not included). Realtime room temperature changes are normal and do not affect incubation. Safe hatching: Builtin egg turning motor and turning plate rotate eggs 45 degrees every 2 hours. Builtin dual fans provide a 360degree thermal cycle, ensuring uniform temperature and improving hatch rate. The transparent enclosure allows observation of development and hatching. An automatic alarm triggers if temperature or humidity exceed preset values. Use scenarios: Home hobbyist: Hatch eggs at home with minimal handson management, suitable for backyard poultry or smallscale egg batches. Educational setting: Ideal for classrooms or science clubs to demonstrate incubation, monitor climate conditions, and conduct handson biology experiments. Small farm or hatchery: Efficiently hatch multiple eggs with reduced manual turning and consistent climate control, supporting smallscale poultry production.
