This handheld probe with a 1/8" shaft and reduced 1/16" (1.5mm) needle tip gives you the exact same high speed probe stem as the Thermapen uses. It's the perfect combination of speed and durability. You get 3 second food or liquid readings. The reduced tip makes a small hole and is perfect for meats and general purpose kitchen use. Reference 103-159 for the straight cable model and 303-159 for the coiled version.
