K Type Thermocouple Surface Probe
K type thermocouple surface probes are flexible, resistant to high pressure, have a quick thermal response time, a long operational life, and a shielded thermocouple extension lead wire with a probe sheath diameter of Φ1.5~Φ8 mm.
Features Of K Type Thermocouple Surface Probe:
K Type Thermocouple Surface Probes are flexible, resistant to high pressure, have a quick thermal response time, a long operational life, and a shielded thermocouple extension lead wire with a probe sheath diameter of Φ1.5~Φ8 mm. In a variety of manufacturing processes, these sheathed thermocouples may directly monitor the temperature of liquids, vapors, gaseous media, and solid surfaces.
Application Area:
K Type Thermocouple Surface Probes can be used for chemical equipment, environmental protection equipment, boiler equipment and vacuum furnace in petrochemical, metal smelting and other fields.
