Refrigeration is one of the most effective and contemporary ways of keeping perishable goods fresh for longer. The length your perishable items stay fresh, on the other hand, depends on how you organize your fridge. You need to ensure that the refrigerator and freezer are adjusted to suitable temperature levels.
Some refrigerators and freezers currently sold in the market come with built-in digital thermometers. You can use the thermometers to set ideal temperatures for the substances you’re preserving. Others refrigeration systems feature dials that you can adjust to lower the temperature levels.
Why Get a Refrigerator Thermometer?
Regardless of the controls found on your fridge or freezer, it’s advisable to get a separate refrigerator/freezer thermometer. The device helps you double-check the accuracy of the inbuilt digital thermometers. You can also to maintain optimum cooling temperatures in the refrigeration units.
The FDA recommends the suitable temperature levels for a fridge to be below 4 degrees Celsius (40 degrees Fahrenheit). You should also set your freezer’s temperature to -18 degrees Celsius (0 degrees Fahrenheit) according to the FDA’s refrigeration requirements. Setting your refrigeration system above these temperature levels can promote bacteria growth on the stored items.
Types of Refrigerator Thermometers
Refrigerator thermometers can either be suited for residential or commercial fridges/freezers. They have different advanced features that make them ideal for their intended application. Here are the key differences and similarities between them.
- Thermometers Used in Residential Fridges/Freezers
Residential refrigerator thermometers help you monitor your fridge/freezer’s temperature levels. They come with integrated magnets and other mounting features that make them easy to mount on your home’s refrigeration system. Most of them usually have lithium-ion rechargeable batteries for power.
The thermometers are designed to give you visual and audible alerts when the temperatures exceed the preset maximum or minimum temperature range. Most of them can also measure temperatures from -40 to 37 degrees Celsius / -40 to 100 degrees Fahrenheit.
- Thermometers Used in Commercial Fridges/Freezers
Though industrial refrigeration systems have advanced technologies for temperature regulation, you still need to get a separate thermometer. The thermometer can help you monitor the fridge and freezer temperature and avoid exposing your perishable goods to improper temperatures. Unlike the ones used on residential fridges/freezers, commercial refrigerator thermometers are built to withstand robust industrial activities.
Commercial refrigerator thermometers have marked dial features that help your read temperature levels in Celsius and Fahrenheit. They also boast of a more compact design that allows them to lay on a flat surface or stand upright when in use. Commercial fridge/freezer thermometers are quite costly than the residential ones.
How to Use a Refrigerator Thermometer
Start by placing the thermometer in your refrigerator or freezer. Provided that the door is closed, you’ll get an accurate temperature reading in a few hours. Consider checking the temperatures in your commercial/residential refrigeration system early in the morning.
Fridges and freezers both have cold spots and warm spots. The door shelves, which are frequently opened, are usually warmer than the back and bottom sides. You need to establish the best temperature balance between these compartments when setting the ideal cooling temperatures for your refrigerator and freezer.
