AcuRite Digital Wireless Fridge & Freezer Thermometer — Dual‑Sensor 00515M with Alarm and Max/Min

Keep perishable foods at appropriate temperatures with a countertop or wall-mounted display that receives readings from two remote wireless sensors — one for the refrigerator and one for the freezer. The compact stainless-steel display can sit on a counter, attach to metal surfaces with its magnets, or hang on a wall. Each sensor relays real-time temperature to the display and stores max/min values so you can review recent fluctuations.

How will this thermometer alert me to temperature problems?

The unit features a programmable audible and visual alarm that activates when either sensor reports temperatures outside the minimum or maximum values you set. Alarms help you notice issues like doors left ajar, power interruptions, or failing cooling equipment so you can act quickly.

• Independent alarm thresholds for fridge and freezer sensors
• Visual and audible alerts on the main display
• High/low memory for each sensor to track recent extremes
• Easy-to-adjust alarm limits on the display unit

What are the mounting and placement options for the display and sensors?

The digital display offers multiple placement choices: a fold-out stand for counters, integrated magnets for attaching to refrigerator doors, and a hang-hole for wall mounting. Each wireless sensor includes silicone straps and suction cups so you can secure them to shelves, walls, or wire racks inside compartments.

• Display: countertop stand, magnetic backing, and wall hang-hole
• Sensors: strap and suction cup accessories for versatile placement
• Compact footprint (4.25" x 3.75") fits most kitchens and service areas
• Stainless-steel look blends with modern appliances

What power and battery choices should I use for reliable readings?

The display runs on three AA batteries while each remote sensor requires two AA alkaline or lithium batteries. For cold environments — notably below −4°F (−20°C) — lithium batteries are recommended to maintain sensor performance in the freezer.

• Main display: 3 AA batteries (not included)
• Sensors: 2 AA batteries each (alkaline or lithium)
• Use lithium in sensors for subfreezing or very low-temperature stability
• Battery-powered design allows flexible placement away from outlets

How does this system help me track temperature history?

Each wireless sensor reports current temperature and retains high and low readings so you can see whether temperatures spiked or dipped over a monitoring period. This max/min memory provides a simple record that can help diagnose intermittent problems or confirm safe storage conditions after an event.

• Separate max/min logs for fridge and freezer sensors
• Quick visual review on the main LCD display
• Useful for reviewing temperature during power outages or door-open events
• No subscription or app required — readings are local to the display unit

Who is this for: The AcuRite 00515M suits homeowners, small restaurants, catering operations, and anyone who needs simple, reliable monitoring of refrigerator and freezer temperatures. It’s designed for users who prefer a battery-operated, no-app solution with visible alarms, straightforward mounting options, and separate sensors for each compartment.
