The Fluke 80PK-3A Type-K Surface Probe, 0 to 260 °C (32 to 500 °F) is designed for measuring the temperature of flat or slightly convex surfaces, with an exposed junction to allow direct contact with the surface being measured. The 40 in. cable is terminated with a Type K miniature thermocouple connector with 0.792 mm pin spacing. The probe can be used with any temperature-measuring instrument that is designed to accept type K thermocouples and has a miniature connector input.
