ITEM NAME:K-Type 1M Thermocouple Probe 5mm x 50mm 2Wire M8 Thread 3.3Ft Temperature Sensor Specifications: Type:K-type Temperature Range: 0 - 500Â °C Thread Diameter: 8mm/ 0.31" Probe Diameter: 5mm/ 0.2" Fork Terminal Spacing: 4mm / 0.2" Probe Length: 50mm / 2" External Shielding : Metal Shield Total Length: 1m/ 3.3Ft Description: 1. Features with 1meters long, 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 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. 1pc Thermocouple.K type Thermocouple with flexible spring built in. 1pc Thermocouple. Probe Length: 50mm / 2". Total Length: 1m/ 3.3Ft. Temperature Range: 0 - 500Â °C. Also note that monitor settings may vary from computer to computer and may distort actual colors.
