Features: Brand new and high quality. The NTC temperature sensor is a high-precision, high-reliability NTC thermistor encapsulated in insulating, thermally conductive, and waterproof polymer materials (sometimes with a housing probe) into the desired shape, extending the lead and combining a set of terminal connections into a thermal sensitivity set for easy installation or remote temperature measurement and control. High sensitivity and fast response. Wide operating temperature range, good stability, and high reliability. Products with different R and B values can be provided, offering strong interchangeability and high precision. Simple structure, easy installation, and good waterproof performance. Applications: Water heaters, wall-hung boilers, ovens, microwave ovens, frying pans, cooking machines, water dispensers, boiling buckets, dishwashers, washing machines, and other household appliances; car air conditioners, refrigerators, freezers; medium and low-temperature drying ovens; thermostats; temperature measurement and control in other situations.
