Traceable® 高精度冷蔵庫用温度計（アラーム付き）

I was worried about keeping my fridge and freezer at safe temps, but the dual probes let me check both zones at once. Setting the hi/lo alarm in 0.1-degree increments took just a minute, and the -58 to 158 range covers everything I need. It's already caught one drift that saved my leftovers.

The alarm is super easy to set in 0.1-degree increments, which let me dial in exactly the right temp for my freezer. Even with the door opening a few times a day, the dual probes keep both zones stable and accurate.

I’ve had mine running for a week now and the 0.1-degree alarm increments give me real peace of mind when storing temperature-sensitive items. The dual probes cover both my fridge and freezer perfectly, and the readings match my standalone thermometer exactly.
