Having to dispose of a bunch of frozen food because of freezer failure is a gut-wrenching experience. A freezer thermometer will alert you to a drastic change in your freezer’s internal temperature and help assure that you never have to deal with such a hassle.
This type of freezer thermometer mounts to the exterior of your freezer or on a wall or shelf nearby. A probe attached to a cord monitors the freezer temp. While you need to be near the freezer in order to hear the alarm, you don’t have to worry about a wireless signal being compromised, and fewer batteries are required than with a remote unit that consists of a sensor and base.
ORIA Refrigerator Thermometer
A sensor is placed in the freezer and a signal is wirelessly transmitted to a base unit that alerts you when the temperature rises above a pre-set limit. This type of thermometer is ideal for freezers located in a garage or shed.
