Features: The WRET-01 and WRNT-01 type compression spring thermocouples tightly attach the thermocouple tip to the surface of the object being measured through a compression spring, enhancing the reliability and accuracy of the measurement. These thermocouples are used in conjunction with display meters and can directly measure temperatures within the range of 0~400℃. They come with flexible extension wires, allowing for free bending, have a short thermal response time, and are easy to use, making them suitable for industries such as plastic extruders, light纺织, and food processing.
