A portable temperature probe. The probe has a handle probe assembly with a longitudinal, steel, antimicrobial, heat-conductive element. A removable, hollow, stainless steel sheath is provided for enclosing and protecting the probe assembly. The heat-conductive element is hardened to resist bending and silver plated for maximum heat-conductivity. The sheath can be carried in a pocket to keep the probe easily accessible, sanitary, and protected from bending. A magnetic closure on the sheath allows the probe to be quickly accessible for removal and storage. The entire unit can be sanitized along with other kitchen utensils without corroding.
