Overview
Not a dial thermometer, this is a compact digital unit with an LCD readout in a waterproof ABS case. It runs on a single LR44 battery, which comes with it.
A quick response and a stored high and low reading help track whether a fridge or freezer stays within safe temperatures. The case wipes clean and is reusable. The listing gives no lower limit or attachment method, which matters for freezers.
Who it's for
Home cooks and small kitchens checking food storage temperature. It suits people who want a record of the extremes between checks. Buyers needing a freezer range figure should check the manual.
Pros and cons
- Stores max and min readings
- Lower range not listed
- Mounting method not listed
- Small display for its size
- Battery type is a coin cell
Performance notes
A digital sensor reads temperature and shows it on the LCD, updating on a short response time. The memory function retains the highest and lowest values since reset. A waterproof case lets it sit in damp fridge conditions.
