Investing in a dependable freezer thermometer is a brilliant way to save money.
This is because...
If your frozen food warms up beyond safe levels, it will spoil, forcing you to trash it.
If on the other hand, the freezer is far colder than it should be, it will become an energy guzzler and lead to needlessly high electricity bills.

While the AcuRite freezer thermometer model # 00515M is the fourth bestselling on our list, it is the # 1 bestselling wireless freezer thermometer.
So what's included in the box?
Why do buyers rave about this important freezer accessory?
With this wireless thermometer set, you don't have to get closer to your freezer or open the freezer door to carry out a temperature check.
Using two wireless, remote thermometer sensors communicating with a remotely located display, you will be able to monitor the temperatures of the relevant environments.
So you could be in your upstairs bedroom and still be able to monitor the temperature of your freezer which could be located in the kitchen, basement or garage.
The key is that display unit is within about 45 feet from the thermometer sensors. Note that solid walls, doors, corners and concrete floors will reduce the working range.
You will also be alerted when freezer or refrigerator temperatures are out of your preset ranges.
This AcuRite thermometer set manages the enviable feat of being in two places at once...
One sensor in the refrigerator and the other in the freezer.
Obviously, the one a picture of a little frost (left in the picture to the right of this text) is for the freezer...
While the one with a drop (right in the picture) is for the refrigerator.
That being said, you can simply have each sensor in a freezer, for a total of 2 freezers.
These sensors then each transmit readings to the digital thermometer display.
The standout benefit of this AcuRite thermometer is that it is a wide temperature thermometer, the widest of all the 5 thermometers reviewed here.
The temperature sensors included with this unit can accurately measure temperatures from -40° F to 99° F (-40° C to 70° C).
The range of tolerance for accuracy on these units is +/- 2°F (+/- 1°C).
This AcuRite instrument doesn't just measure and relay temperature readings to you.
The programmable alarm notifies you audibly and visually when temperatures exceed your set minimum or maximum range.
It also alerts you to temperature spikes caused by mistakenly leaving the fridge or freezer door open, or when the appliance fails, causing the temperature to rise, dip or fluctuate.
When the alarm goes off, pressing the alarm button on the display silences the alarm for 5 minutes or until you insert the sensor back in the fridge/ freezer and the sensor gets back below the set point.
The alarm function is especially helpful because it enables you to take timely action to avert food spoilage.
As you already know, spoiled trashed food = wasted money. On the other hand, consuming spoiled food leads to foodborne diseases such as E coli, Hepatitis A, Nontyphoidal Salmonella, Norovirus, Shigella, Salmonella Typhi.
So an alarm plays a crucial role in thwarting both the above.
Each sensor is powered by 2 AA alkaline or lithium batteries (not included).
Lithium batteries are highly recommended for use in sensors for temperatures below –4 degrees Fahrenheit (-20 degrees Celsius) because the alkaline batteries cannot withstand colder temperatures and will die.
One wireless refrigerator thermometer and one Wireless freezer thermometer digital display is powered by 3 AA batteries.
The AcuRite Freezer Thermometer 00515M sensors on the one hand, and display unit on the other, can operate over a wide distance.
What is the maximum range or distance between each sensor and display unit?
The sensors need to be placed within 75 feet of the display unit…
The signal between the transmitter and receiver is strong and you won't loose it plus there is a dip switch giving you the option of three different channels.
Great range as I have it upstairs, where I typically am and the freezer/fridge units are a floor below and the range is easily handled.
Bear in mind though that the signal range can be impacted by sensor location and whether it has to maneuver its way through solid walls or concrete floor.
Does the display indicate if it's still communicating with the sensors?
Yes, below the temperatures, along the edge of the display on either side is a “Signal Strength” icon for each sensor.
It should show four solid bars along with a bar that looks like a “T” for excellent signal strength...
If no bars are present, it means the signal to the sensors has been lost.
This AcuRite freezer thermometer is a digital thermometer (not an analog one!).
As a digital thermometer, this offer 3 main advantages:
This thermometer has a big and bold "digital font" that is easy to read.
It is especially appropriate if your eyesight has begun to wane.
The white thermometer sensors can be installed in either of 2 easy ways:
The thermometer display conveniently offers 3 installment options:
The digital display is powered by 3 AA batteries. Each sensor is powered by 2 AA alkaline or lithium batteries.
Lithium batteries are highly recommended for use in sensors if these are going to be placed in environments with temperatures below -4 degrees Fahrenheit (-20 degrees Celsius).
The batteries are not included so be sure to order them separately.
The thermometer display's modern, brushed stainless steel finish is an elegant addition to any home or commercial kitchen.
And, the white sensors will blend into the interiors of most fridges and freezers.
You'd think that a thermometer set that offers all of the above benefits would weigh a ton.
Far from it!
This freezer thermometer set weighs just 13.4 ounces.
The dimensions of the display are just 4.25 IN x 3.75 IN so it won't stick out like a sore thumb on the fridge/ freezer door, countertop or wall.

The two thermometer sensors measure and report the temperature in one freezer and one fridge.
Or you can install these sensors in 2 freezers, instead, rather than in a refrigerator and a freezer.
These readings are then relayed to the thermometer display unit where the temperatures are—well—displayed.
