Food Service Thermometer 50-550°F

The Cooper Atkins 3270-05 is an analog mechanical stem thermometer built for professional food service environments. It measures temperatures from 50 to 550 degrees Fahrenheit with an accuracy of plus or minus 1 degree Fahrenheit. The 2 1/2 inch dial provides clear readings for deep fryer and general cooking applications. It is designed for direct food contact and features a stainless steel case.

Metal Detectable Stainless Steel Construction

The thermometer uses a stainless steel case and stem that are metal detectable, reducing foreign object contamination risk in food processing lines. A 1/4 inch overall diameter stem suits standard probe insertion points. The unit carries a one year manufacturer warranty but does not hold NSF certification. These material choices support durability and safety compliance in commercial kitchens.

Simple Stem Installation With Calibration Checks

Installation requires inserting the stem into the product or oil until the sensing area is submerged, then reading the analog dial. No power source or complex setup is needed. Common issues include physical damage to the glass lens or stem bending, which affects accuracy. Users should verify calibration regularly using ice water or boiling water reference points to maintain the stated tolerance.

Questions about this item

Does the stainless-steel stem need any calibration after months in a deep fryer?

The analog dial is rated at ±1 °F accuracy; mechanical thermometers of this type hold calibration unless the stem is bent or corroded, so periodic ice-point checks are the only routine step.

What stops the dial from fogging or the stem from warping during continuous 550 °F service?

The ¼-inch stainless-steel stem and 2 ½-inch dial are built for sustained deep-fryer temperatures up to 550 °F; the limit is the metal’s heat tolerance, not an electronic component.

How hot does the case get and does it need extra clearance in a busy fry station?

The stainless-steel case reaches fryer temperature, so it radiates the same heat as the oil; no internal power source adds extra warmth, but operators should treat the dial area as a hot surface.
