Easy to switch between cool and heat modes: Set the target temperature and a differential value to automatically regulate the environment, reducing the need for constant manual adjustments. Precise temperature control: Includes a temperature calibration function to deliver accurate readings and stable performance. Wide application: Suitable for aquariums, terrariums, zoos, paludariums, and chicken incubators, offering flexible use across different environments. Safety and reliability: Enhanced refrigerating control output delay provides added safety and smoother operation. Why you need it: Maintains a stable temperature within a defined range, minimizing fluctuations that can stress aquatic and terrestrial habitats and improving overall enclosure management. Use scenarios: In an aquarium, keep water temperature within a narrow band to support fish health and consistent metabolism. In a terrarium or paludarium, provide reliable heating or cooling to maintain appropriate humidity and temperature gradients for reptiles and amphibians. In a chicken incubator, ensure steady incubation temperatures for better hatch rates and uniform development.
