Replace a lost or damaged temperature probe or add a new one to your existing tool kit with this STEELMAN 97900 1-Inch Analog Dial Bimetallic Stainless Steel Temperature Probe. The single scale display has easy to read black on white markings that contrast great against the bright red indicator needle. Designed to show temperatures only in farenheit, the 1-inch diameter dial face has markings to cover a range of 0 to 220 degrees. This stainless steel tool has a bimetallic design that operates reliably without the need for batteries or external power and can be easily recalibrated with a wrench and a cup of ice water thanks to the hex nut on the back of the display. When not in use, the probe comes with a convenient red plastic sleeve for easy storage and to prevent accidental punctures. The sleeve features a handy pocket clip as well so you can keep it safe in a pocket between uses.
