Maverick CT-03 Oil/Candy Fryer Thermometer Review

This thermometer is designed for measuring temperatures of candy and oil. It has a clip to mount the unit on the lip of a pot, good accuracy, and a low price. The readout head is articulated to make viewing easy, and has a stainless steel protective cover to avoid heat damage. There is no backlight.

This unit has a rounded tip instead of a sharp point like meat thermometers. The probe length is generous at 8″ (20cm). The unit displays the current temperature in either F or C. There are two modes: candy and frying. The user first selects the mode, then selects the temperature range appropriate to the food being prepared. The LCD display of the text in these ranges will require eyeglasses for all but the most visually endowed. (These are also displayed on the rear of the unit. Wear your glasses!) When the temperature rises to that setting, a beeper will sound and the temperature display will flash.

The unit will stay on as long as the temperature is above 130ºF (54ºC), otherwise it will auto-shut-off after 3.5 minutes.

The manufacturer’s address for warranty returns is shown on the instruction sheet. The unit is covered by a 90-day limited warranty.

This is an inexpensive unit designed for a single purpose, which it accomplishes. It’s operation is basic, but so is the process. We’ll give it a Silver medal for functionality, quality of construction, and value.

3) Tell us everything we need to know to help such as the type of cooker and thermometer. Dial thermometers are often off by as much as 50°F so if you are not using a good digital thermometer we probably can’t help you with time and temp questions. Please read this article about thermometers.
