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 working modes: heating (start temperature is lower than stop temperature), cooling (start temperature is higher than stop temperature), accurate and reliable, and good long-term stability.</ p> High Precision: 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 precision, 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 you just need to set the start temperature and the start temperature. stop to be programmed. Applications: Waterproof probes can be used for home brewing, refrigerators, pet feeding, reptile tanks, incubation, fermentation, seedling heating pads and accelerated germination. You can also set time delay and low/high temperature alarms. 24V
