RIY Waterproof Digital Refrigerator Thermometer

Overview

This is a digital refrigerator and freezer thermometer with a large LCD screen and a waterproof rated housing. It is built for anyone who wants a numeric temperature readout instead of a dial.

The sensor sits on the back of the unit, so it reads the air directly behind where it is mounted, either hung on a hook, held by magnet, or set on its fold out stand. It tracks minimum and maximum temperatures since the last reset, which is more useful for catching an overnight spike than a single point in time reading. The stated accuracy is plus or minus 2F, wide enough that it should be treated as a guide rather than a lab measurement.

• -4F to 122F measuring range
• IPX3 waterproof rated housing
• Runs on one included CR2032 battery
• Protective film must be peeled off the screen before use

Who it's for

Shoppers who want a numeric LCD readout and a min/max log for a fridge or freezer, rather than a mechanical dial, fit this. It suits home kitchens as well as bars, cafes and small commercial coolers per the listing.

Pros and cons

Performance notes

The sensing point sits on the back of the housing, so accuracy depends on how it is mounted; hanging it inside the fridge rather than on the door is said to give a truer reading. It runs on a single CR2032 battery and holds an IPX3 waterproof rating, meaning it can handle incidental moisture from a fridge interior but is not meant to be submerged. Its stated range is -4F to 122F with about 2F of tolerance in either direction.
