Material: Made of sturdy flame retardant ABS plastic, designed with compressor delay protection, perfect use in various fields, convenient operation and convenient settings. High Efficiency: Two modes of operation: heating (the start temperature is lower than the stop temperature), cooling (the start temperature is higher than the stop temperature), precise and reliable, and good long-term stability. < p>High Accuracy: The digital temperature controller can measure and monitor temperature in real time. The measurement accuracy is ±0.1°C, the control accuracy is ±1°C, and the temperature control range: -50~99°C, with high accuracy, high sensitivity and high stability . specialty. Easy to Use: Easy to connect and program, first connect the controller and the heating or cooling equipment to the power supply, then connect the temperature probe, and finally it you just need to set the start temperature and stop temperature to schedule. Applications: Waterproof probes can be used for home brewing, refrigerators, pet food, tanks reptiles, incubation, fermentation, seedling heating pads and accelerated germination. You can also set time delay and low/high temperature alarms.
