Specifications:Type: k-typeTemperature Range: 0 - 500°cThread Diameter: 8mm/ 0.31"Probe Diameter: 5mm/ 0.2"Fork Tip Spacing: 4mm/0.2"Probe Length: 50mm/2"External Shielding: Metal ShieldingOverall Length: 1m/3.3ftDescription:1. Features with 1 meter length, 8mm thread diameter, 5cm probe length thermocouple.2. A thermocouple is a device consisting of two different conductors (usually metal alloys) that produce a voltage proportional to the temperature difference between each end of the pair of conductors.3. The grounded type is more sensitive to temperature, it can help you measure the temperature quickly.4. K-type thermocouple with built-in elastic spring.5. 2 terminals for easy connection. The temperature measurement range is from 0 degrees Celsius to 500 degrees Celsius.3. Widely used in industry or laboratory to test the temperature of equipments. Package Included:1pc Thermocouple
