Dual-channel fridge monitor
This digital thermometer tracks refrigerator and freezer temperatures at the same time using two channels. It refreshes readings every 10 seconds and offers ±1 / ±1.8 accuracy. The white unit mounts with a magnetic back and includes visual and audible alarms when temperatures drift outside your set range.
Home kitchens and lab storage
Suitable for households that want a simple alert when a fridge or freezer moves out of safe limits. Also works in medical, commercial or laboratory settings where a custom range between -40 and 70 °C is required. Not for users who need data logging, wireless connectivity or a calibrated certificate for regulatory audits.
Factory presets and custom range
Preset zones cover refrigerator 0-8°C / 32-46.4°F and freezer -18 / -0.4°F. You can adjust thresholds across the full -40~70 °C / -40~158 °F span with one-temp calibration. Power comes from two AAA batteries (not supplied) and a low-battery buzzer warns before monitoring stops.

Questions about this item
How do I install the thermometer and what step do people often miss?
Mount the unit using the magnetic back on the fridge or freezer wall, then insert two AAA batteries — the product ships without them, so this step cannot be skipped.
What maintenance will the thermometer need later?
Replace the two AAA batteries when the low-battery buzzer sounds continuously; no other routine maintenance is required.
What limit appears first during sustained use?
The screen refreshes every 10 seconds, so temperature changes faster than that interval will not be shown until the next update.
