Listed at 6.79 USD. - Product Name : Thermocouple Probe - Type : K Type - Temperature Range : 0℃ - 400℃ - Temperature detection form: plug-in Description: 1. Features with 1/2/3/4/5meters long, 8mm thread diameter, 30mm / 50mm / 100mm / 150mm / 200mm probe length thermocouple. 2. 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. 3. Grounded 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 celsius to 500 celsius degree. 3. Widely used for industrial or laboratory to test equipments temperature.
