Feature: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 0120C.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 SensorMaterial: CopperMounting Thread: M 14 x 1.5Measuring Range: 0-120CAlarm Temperature: 96C.Package List:1 xWater Temperature Sensor
