Temperature measurement range is from 0 celsius to 800 celsius degree. Grounded type is more sensitive to temperature, can help to measure temperature fastly. K type Thermocouple with flexible spring built in.2 terminals for easy connection. A thermocouple is a device consisting of two different conductors (usually metal alloys) that produce a voltage proportional to a temperature difference between either end of the pair of conductors. Widely used for industrial or laboratory to test equipments temperature., Weight: 0.55666721155 pounds, Manufacturer: Kueohse
