The plastic thermometer tracks the high and low temperatures recorded for the fridge and the freezer, you can easily monitor the temperature change of your refrigerator and provide double protection to your food safety. Attached this aquarium thermometer on the outside of your tank with a suction cup. submerge the probe in the tank where you want to measure water temperature and attach that with a suction cup. Then just press the power button on the screen anytime you need to take a reading. Small size and lightweight design for convenient placement in any refrigerator or freezer.
