U UNNI Digital Refrigerator Thermometer with Alarm – Wireless Fridge & Freezer Temp Monitor

Comprehensive Temperature Monitoring for Home and Small Kitchens

The U UNNI Refrigerator Thermometer with Alarm blends precise sensing with flexible placement. Using a Swiss-made sensirion sensor, it reports temperatures from -40ºF to +158ºF with an accuracy around +/-1.8ºF. The device supports multiple mounting options: a back magnet, a foldable stand, a hanging hole, and an unobtrusive profile that fits on a door, shelf, countertop, or pantry corner.

Two temperature alerts with a 90 dB alarm notify you of shifts quickly, while you can read exact values at a glance without opening doors. The readings cover both fridge and freezer compartments, and the max/min records help you spot trends over the day or across days.

Power, visibility, and flexibility

Power options include USB and battery, letting you choose based on space and use. The 4.5 inch display is easy to read, and the backlight offers three brightness levels for day or night viewing. When powered by USB, the backlight stays on; on battery, the display lights for a short period.

• Long-range wireless transmission up to 328 ft / 100 m keeps placement flexible
• Data refresh every 30 seconds for near real‑time monitoring

What you get and how it helps

The thermometer ships with two sensors, hooks for mounting, a USB cable, and a one-year warranty. You can track the fridge and freezer temps separately, and switch between 24h mode or all-time mode with automatic daily resets. This setup supports quick checks during busy shifts in home kitchens or small restaurants.

• Two sensors provide distinct fridge and freezer data
• All-time and 24-hour modes help you observe short-term changes or longer trends

Real-life use cases

Place the device on a shelf beside dairy and meat storage, or attach it to a door for instantaneous visibility when you restock. Its compact size and clear display make it a practical companion for meal prep, beverage coolers, and wine or produce storage areas. It is designed to be reliable, noninvasive, and easy to read at a glance.

Note: this is a temperature monitoring tool and should be used as a guide for maintaining proper storage conditions. Always follow food safety guidelines and use your best judgment.
