Description: 1. Features with 1meters long, 8mm thread diameter, 5cm probe length thermocouple. 2. A thermocouple is consisting of two different conductors (usually metal alloys) that produce a voltage proportional to a temperature difference between either end of the p of conductors. 3. type is more sensitive to temperature, can help to measure temperature fasterly. 4. K type Thermocouple with flexible spring built in. 5. 2 terminals for easy connection. Temperature measurement range is from 0 to 500 degree. 3. Widely used for industrial laboratory to test equipments temperature.
