K-Type Thermocouple Probes
K-type thermocouple probes are equipped with shielded lead wire, stainless steel probe diameter 1.5 ~ Φ8mm, can directly measure the temperature of liquid, steam and gas medium and solid surface in various production processes, ranging from 0 ℃ to 1300 ℃.
Features And Advantages Of K Type Thermocouple Probes:
K Type Thermocouple Probes are currently the largest consumption of metal thermocouple, its consumption is the sum of other thermocouples. K type thermocouple wire diameter is generally 1.2mm ~ 4.0mm. K Type Thermocouple Probes have shielded lead wire and sheath diameter probeФ1.5~Φ8mm, with flexibility, high pressure resistant, fast thermal response time and long operating life. These sheathed thermocouple can directly measure the temperature of liquid, vapor, gas medium and solid surface in various production processes. K-type thermocouple has the advantages of good linearity, large thermoelectric emf, high sensitivity, good stability and uniformity, strong oxidation resistance, low price and so on.
Application:
Electric Furnace Temperature Measurement, Medical Equipment, Smelting Furnace, Disinfection Cabinet, Refrigerator, oven and other equipment that need to detect and control temperature.
