The Oakton Thermocouple probes were designed to measure any general-purpose or liquid immersion application. All thermocouple probes include a 5-ft. PVC coiled cord with strain relief that protects from repeated flexing and tugging. Finger stops on handle prevent probe from rolling and fingers from sliding when inserting probe into hard materials. Rugged plastic mini connector is compatible with all Oakton Digi-Sense and Acorn thermocouple thermometers.
