AcuRite Digital Wireless Fridge & Freezer Thermometer with Dual Sensors, Alarm and High/Low Memory

Keep cold storage conditions visible and under control with a single display that reports temperatures from one refrigerator sensor and one freezer sensor. The system helps you spot temperature swings quickly, stores the recorded high and low readings for each compartment, and offers multiple mounting options so you can place it on a counter, attach it magnetically to an appliance, or hang it on a wall.

How does this setup protect food stored in the fridge and freezer?

The device continuously monitors both compartments and sounds an alarm if temperatures move outside your set minimum or maximum range. By logging high/low values, it helps you review when excursions happened so you can respond to thawing or cooling failures faster.

• Dual wireless sensors: one for fridge, one for freezer.
• Audible and visual alarms for out-of-range temperatures.
• High/low memory to track temperature history per sensor.
• Immediate alerts for open doors or appliance malfunctions.

How easy is it to install and place the sensors and display?

Installation is straightforward: the display runs on three AA batteries and can sit on a counter, mount to metal with its magnetic backing, or hang using the integrated keyhole. Each sensor connects wirelessly and can be fastened with included suction cups or wrapped with silicone straps around shelving.

• Display: countertop stand, magnetic back, or wall keyhole.
• Sensors: silicone straps and suction cups for versatile mounting.
• Batteries: display uses 3 AA; sensors use 2 AA each (not included).
• Recommended lithium cells for sensor use below -4°F (-20°C).

What alarm and display features can I customize?

Set separate minimum and maximum thresholds so the unit only alerts you when temperatures cross the ranges you choose. The LCD shows current readings for each sensor and preserves recorded highs and lows for easy review.

• Programmable high and low temperature limits per sensor.
• Audible beep and visible indicator when limits are exceeded.
• Clear LCD readout showing both fridge and freezer temperatures.
• Memory of peak and low values for each remote sensor.

What materials and power requirements should I plan for?

The display has a modern stainless-steel finish to match contemporary kitchens and uses three AA batteries so it’s fully wireless. Each remote sensor requires two AA batteries; for reliable low-temperature performance in freezers, lithium batteries are advised.

• Display finish: stainless-steel styling for kitchen integration.
• Display power: 3 AA batteries (not included).
• Sensor power: 2 AA batteries each (not included); lithium recommended for extreme cold.
• Limited one-year manufacturer warranty included.
