Usage Tips:Features: 1.Resistance Control: The higher the water temperature, the lower the resistance value. The lower the water temperature, the greater the resistance value. 2.Alarm: When the water temperature reaches the alarm temperature, the alarm light is on. When the water temperature drops, the alarm lights go out. 3.Quick Response: When the alarm temperature is reached at 96C, the alarm light is on and the response time is about 1 second, the measuring range is 0?120C. 4.Installation: There are 2 wires, one connected to the water temperature meter, displaying the water temperature parameters, and one connected to the alarm switch. 5.Fine Workmanship: Professional manufactured, exquisite workmanship with unique design, ensure stable performance and high reliability. Specification: Item Type: Water Temperature Sensor Material: Copper Mounting Thread: M 14 x 1.5 Measuring Range: 0-120C Alarm Temperature: 96C PackageList: 1 x Water Temperature Sensor
