The 80PK-26 SureGrip TM Tapered Temperature Probe is essentially a bead probe with a handle that can be used as a surface probe. The stainless steel sheath allows the bead to measure temperatures higher than bead probes with flexible leads. The handle also allows you to apply more focused surface pressure without having your hand in close proximity to the source. The 40-inch (1-meter) cable is terminated with a Type K miniature thermocouple connector with 0.792-mm (.312-in) pin spacing. The 80PK-26 can be used with any temperature-measuring instrument that is designed to accept Type K thermocouples and has miniature connector input. Type-K thermocouple with tapered tip for use in air, non-caustic gas and surface applications Measurement range:-40 to 816ºC
