Built in thermistor, with excellent temperature sensitivity, can accurately detect subtle changes in water temperature, allowing the coffee machine to brew coffee strictly according to the set temperature. Supporting flexible of water temperature, it can accurately fit the corresponding water temperature according to the needs of different coffee brewing methods such as hand brewing, espresso. Equipped with a dedicated boiler circuit, it can monitor the temperature condition of equipment in real time, ensures stable operate of coffee machines and other equipment. The output signals is stable, and it is not easily affected by external interference during long-term use. The measurement results are stable and suitable for high-temperature working environments of the equipment. The temperature probe can accurately control the start and stop of the heating component. When the water temperature reaches the set standard, it can promptly control the heating component to stop working, effectively energy waste.
