Freezer Monitoring That's Simple and Easy

Freezer monitoring systems help users maintain optimal freezer temperatures, even without being present in the room. 

These systems are commonly used in hospitals and other facilities that store sensitive equipment. There are many different tools and features included in freezer monitoring. 

Having an alarm for a freezer door is one of the best ways to monitor your freezer remotely as it can help your team quickly distinguish between an accidental door left open and a genuine freezer on the fritz. 

Your freezer door alarm can alert you when you’ve left the door open or when the temperature inside has reached dangerous thresholds. 

You can set your freezer alarm temperature to whatever you want so that when temperatures dip below that number, you will receive an immediate alert and act accordingly.

So what is the best freezer alarm, and what should you be looking for when choosing a device like this? 

The best freezer alarm for your business will likely depend on your specific needs. 

If you’re looking for something that can be connected and monitored  over Wi-Fi, you should look for the best freezer alarm with Wi-Fi. 

Likewise, if you require adjustable delay capabilities, you should look specifically for a fridge alarm with adjustable delay. 

A wireless freezer alarm can be a great option for those that want the freedom to configure their alarms as they choose. Sonicu delivers its alerts via text, email, push notification and even phone calls, connecting with customers across a diverse array of platforms so they don’t miss a critical alert. 

Sonicu’s wireless temperature monitoring solutions allow users to protect their most valuable assets and ensure that required environmental temperatures are maintained at all times. 

With Sonicu, you can protect lab freezers, freezers that hold food, and more. 

With the amount of people working remotely these days, it’s important to ensure building safety, and Sonicu enables users to monitor freezers around the clock, no matter where they’re working from.

Walk-in Cooler Temperature Monitoring System

A walk-in cooler temperature monitoring system can be a great choice for those with walk-in coolers or freezers. Learning how to monitor freezer temperature remotely is critical for those that frequently work away from their facilities. Or for those who believe, with good evidence, that a walk-in fridge or freezer could fail at night or on the weekend. 

It’s not enough to simply check back the next morning and hope that all required conditions have been maintained—you have to actively monitor it on a constant basis, and temperature monitoring systems allow you to do so in a way that’s both easy and effective. 

You can connect these systems to other devices in order to keep close tabs on them and ensure that all proper safety protocols are followed. You might also look at systems that are reliant on Wi-Fi if you’re trying to avoid a bunch of cords and wires. 

Sonicu also offers connectivity via cellular and our proprietary SoniLink hub that can connect many points of monitoring with a single hub that communicates all the data to the cloud via cellular or ethernet connection. 

A commercial freezer temperature alarm Wi-Fi sensor can operate seamlessly through Wi-Fi, as can a walk-in cooler temperature sensor Wi-Fi alarm. 

These are both great options for businesses that prefer Wi-Fi-based systems over other types of monitors.


Commercial Freezer Temperature Monitoring System 

If you work in a commercial building and are responsible for storing temperature-sensitive items, a commercial freezer temperature monitoring system is a must. 

The type of system you choose will depend on the facility you work in. 

For example, if you work in a lab, you should look specifically at laboratory freezer temperature monitoring systems, as these will be best suited to meet your needs. Sonicu serves scores of laboratories - both public and private - thanks to the system’s ability to deliver automated reports to satisfy virtually any regulatory body. 

From the FDA to the USDA and third-party auditors, Sonicu has developed a simple reporting platform that helps laboratories meet inspectors’ stringent requirements. 

You should also search based on whether or not you’d like the system to be Wi-Fi-based. 

A Wi-Fi freezer temperature monitoring system can be more convenient than others, as it allows users to monitor their rooms at all times, even if they’re working remotely. 

A wireless temperature monitoring system can also be helpful for those that prioritize convenience.

Not all refrigeration alarm systems are built equally, so it’s important to consider your ultimate purpose for a temperature monitoring sensor. 

How are you hoping that a system like this will improve your monitoring capabilities? 

Do you frequently work remotely, or are you on-site most of the time? 

Different systems are built for different types of workers and facilities, which is why you should outline your specific needs before starting your search.


Freezer Monitoring Compliance Agencies

Refrigerator Temperature Monitoring System

Learning how to monitor freezer temperature remotely does not have to be difficult even for those that haven’t previously worked with this kind of technology. 

It can save you time and allow you to be more efficient with the resources at your disposal. 

A refrigerator temperature monitoring system is especially critical for those that work in hospitals, as they are responsible for large numbers of sensitive equipment and medications. 

Scores of hospitals, including Hancock Regional Hospital and Hendricks Health, rely on Sonicu to support virtually all of their temperature and environmental monitoring needs. 

From the nutrition department to compounding rooms in the pharmacy, Sonicu helps these complex healthcare organizations improve the way they deliver patient care, meet regulatory obligations and drive down labor costs associated with tedious manual logging. 

 A hospital refrigerator temperature monitoring system is essential for facilities such as these. 

Without a Wi-Fi freezer temperature sensor, it can be incredibly difficult to keep up with temperature conditions at all times, which can spell disaster for your equipment.

One of the great things about having a refrigeration monitoring system is that it can feed you detailed reports on changes in temperature. It’s important to know how conditions change overnight or whenever you aren’t working at the facility. 

This can let you know whether or not you need to make changes to the sensor or even invest in a new system altogether. 

Needless to say, it can be difficult, if not impossible, to keep up with these changes entirely by hand, which is why having an automatic monitoring system can be so valuable. 

Ultralow Freezer Temp Monitoring

Remote Fridge Temperature Monitoring

Remote fridge temperature monitoring is the process by which facilities monitor their fridge temperatures remotely. 

This can be done in many different ways but is most commonly achieved with a remote fridge temperature sensor or freezer alarm that connects to a phone.  WTF?!? 

With an app, you don’t have to download expensive or complex software in order to access your monitoring system.

This can be particularly helpful for those that work on the go.

Having a freezer temperature monitoring system is absolutely crucial for those that work in healthcare facilities. 

Proper storage of medical equipment and medications is vital to the safety of patients and staff alike. 

If you manage a facility like this, it’s important to find the best Wi-Fi refrigerator monitoring system  in order to stay updated on the status of your refrigerator, even when you are unable to monitor the temperature in person. 

This will at least keep you in the loop and make you aware of any major differences in temperature that have occurred since you last used the fridge.

Upright Freezer With Alarm

An upright freezer with an alarm can be extremely valuable to facilities that store temperature-sensitive items. 

A freezer with a temperature display can be especially helpful for easily determining the current temperature in the freezer. 

Instead of having to measure the temperature by hand, you can take a quick glance at the display to see what conditions are like inside the device. 

A freezer alarm Wi-Fi sensor can alert you to dangerous changes in temperature when you are away from the facility and no longer looking directly at the display. 

Sonicu’s mobile app is the ideal complement to an external display in that it allows you to keep an eye on your temperature regardless of your physical location. 

An outlet alarm for your freezer can alert you when the power goes out in your fridge. This is crucial, as it can be difficult to check the power status otherwise, especially if you’re working remotely. 

There are many different components of freezers that should be monitored to ensure temperature safety, and having different tools and sensors can help you keep track of all of these elements. 

Selecting and installing and installing a monitoring system does not have to be difficult, , 

Commercial Freezer Alarm On Your Phone

Commercial Freezer Alarm

There are multiple types of commercial freezer alarm systems, so no matter the extent of your needs, you should be able to find something that is right for your business.

You might use a chest freezer with a temperature alarm if you prefer chest freezers, and you might look for a freezer alarm that connects to your phone if it’s important that you be able to access your system remotely. 

Freezer alarm Wi-Fi systems are a great option for those that prefer working over Wi-Fi; a walk-in freezer door alarm may be best for those that work with large, walk-in freezers. 

The bottom line is that when it comes to freezer alarm systems, you have a wide range of options available to you, so it’s important to do your research to find the one that’s most aligned with your unique needs. 

When choosing a commercial freezer door alarm, it’s a good idea to focus on systems that provide detailed reporting. 

Sonicu’s automated remote temperature monitoring kits monitor and log data around the clock and can help you stay on top of refrigerator safety, no matter where you’re working from. 

With the SoniCloud mobile app, you can easily access features, receive 24/7 notifications, and more. 

This can help prevent asset loss due to power outages or equipment failure.

and then every now and then you just get a bad boy who doesn’t want to perform as we need it to,”
Martha Rardin, Director, Nutrition and Dietetics, Hendricks Regional Hospital.

Tim Livesay - Hancock Regional Hospital Pharmacy Director“Sonicu has been a powerful tool to identify which units are behaving out of spec and get our team
to fix them before we have a serious issue.”
