Freezer & Refrigerator Temperature Monitoring System


It is crucial to record the temperature and humidity of medical refrigerator and freezers used for critical items, such as: medicine, vaccine, plasma, blood samples etc. If the temperature rises or falls above or below the permitted levels, the operating personnel should be notified. The customer can have from centralized monitoring, recording, and protection of hospital refrigerators and freezers. Our medical freezer temperature monitoring systems will continuously monitor and record. They have an accuracy of up to 0.1 degrees Celsius. We can monitor multiple units in various parts of a building. We can also connect to an existing LAN or Wi-Fi network. As a result, all the data from each medical refrigerator will be always available on a PC or via the internet. This system is appropriate for centralized monitoring of medicines, vaccines, human tissues, samples, food, and other items stored under controlled conditions. With expansion units, the same system can be used for walk-in chillers, cold rooms, medical fridges, warehouses, and other applications.temperature-recording-and-alert-for-refrigerator

Refrigerator & Freezer Temperature Monitoring System With Alerts

We can install remote medical temperature monitoring system for freezer with alarms on all types of medical refrigerators and freezers, new and old. The display unit can be mounted on the outside of the medical fridge. We will install the temperature sensors for freezer inside the units either through the wall or through the door gaskets.

Features of refrigerator temperature monitoring with Alarm

The temperature of the medical refrigerator is recorded by this data logger. Additionally, it triggers alarms via an electrical contact (We also have cloud-based alert systems).

  1. Any connection to already-existing installations is acceptable.refrigerator-monitoring-scheme-drawing-fullsize
  2. A wireless system that won’t interfere with the hospital’s operations is ideal for hospitals.
  3. There are wired and wireless data logger models available. These refrigerator temperature monitoring system with alarms for medical refrigerators use sensors that can communicate via Wi-Fi, RF, or Zigbee protocol.
  4. They have a +/- 0.1 degree accuracy range. Celsius. This is comparable to every other data logger out there for uses like yours.
  5. The sampling rate can be programmed to range between 5 seconds and 1 hour. A sampling interval of one to three minutes is sufficient for monitoring the temperature of a medical refrigerator.
  6. Each device for each medical refrigerator can be individually programmed. Programming is done for the temperature’s upper and lower bounds. Additionally, different threshold limits may apply to various compartments of a single medical refrigerator. Alerts will be generated if the readings go above these limits for a specific amount of time.
  7. Each device can be linked to two nearby medical refrigerators. Additionally, two different compartments of the same medical refrigerator can be connected. Therefore, one device can monitor two refrigerators that are close to one another. Up to 10 refrigerators can be connected to one device using one of our various models.
  8. The local temperature monitoring system with alarm emits an audible alarm in response to an alert event, can be connected. Each refrigerator alarm can be connected separately to each unit. As an alternative, we can offer a shared alarm for a room with multiplerefrigerator-temperature-monitoring-alarm units.
  9. A standby system could be an additional phone call (with a voicemail), email, or SMS alert system. It dials a different number for every refrigerator alarm.
  10. Without the need for a static IP address, we store the data on our free web storage (This is applicable to certain models only).
  11. The sensors allow for measurements down to -200 degrees Celsius. These are for use in cryogenic environments.
  12. To prevent erroneous alerts when opening the medical refrigerator’s door repeatedly, it is preferable to configure a delay timing. Additionally, submerging the sensor in a unique liquid, like glycol, is ideal. This will serve as a dampener to prevent false detection of such abrupt fluctuations (for more information, please see our article on the use of liquid glycol/glycerin bottles in a medical refrigerator).
  13. Keeps track of the humidity and temperature in various freezers and refrigerators. The system is cloud-based, so there is no cap on the number of connected refrigerators.
  14. The customer can remotely access the data: Watch a video of some free browser-based software.

A phone call, SMS, Email alerts and local Alarm for Temperature excursions of Refrigerator & Freezer

The following alerts will be generated in the event of a temperature excursion.

  1. It will make 10 operator phone calls in a sequential order. When the call is answered, it will play a personalized voice message. The type and location of the fault will be included in this message. When no one answers the phone or returns the call, the machine will attempt to contact.
  2. Depending on the kind and location of the fault, it will send SMS messages to the same operators or a different group of operators. We can set up the SMS to include both the locations and the precise temperature at the incident’s time.
  3. It will email four email addresses alerts with the current time, location, and temperature readings.
  4. To alert local operator or security personnel, you can also connect a local siren.

Refrigerator temperature monitoring through Wi-Fi monitoringRefrigerator-temperature-monitoring-wireless

These characteristics are all present in the Wi-Fi system. The main distinction is that WiFi communication channels are used for the communication. No unique transmitters or receivers are needed for it. The exchange of information will take place over an active WiFi network. The medical refrigerator temperature monitoring system will transmit data continuously from each temperature data logger. The customer has the option to schedule transmission for intervals like once every 60 seconds. Both the internet and a local server network will receive data from it. For flexibility, we advise WiFi or Wireless connections for medical refrigerators. The refrigerators might need to be relocated or moved frequently. You’ll also need to remove it for maintenance or repairs. You do not need to worry about disconnecting and reconnecting the LAN connection in the case of wireless connections.

Guidelines on how to select a monitoring system for refrigerators and freezers

You can use the following guidelines to choose the type of monitoring system:

    1. First, you must choose whether to record only the temperature or whether humidity is also necessary. In most cases, you only need to record the temperature. A refrigerator’s interior humidity will always be high due to frequent door opening. Furthermore, it is challenging to regulate the humidity level inside a refrigerator.
    2. You could choose a small device with a single sensor and WiFi connectivity if you have single refrigerators spread out across different rooms. It’s possible that you don’t want wires to cross between rooms.
    3. You might choose a system with four sensors if you have three to four refrigerators in the same room.
    4. You might have noticed that one temperature sensor for freezer is required for each compartment. Therefore, two sensors are required if a refrigerator has two compartments with independent doors.
    5. You should consider a system that can connect to a large screen if you have eight or more refrigerators in the same room. You can view the alert and all the readings on one screen in this situation.
    6. Each refrigerator’s phone call alerts may not be necessary. Depending on how vital the items in each medical refrigerator are, you can make this determination.
    7. Battery-backed devices are necessary if your power supply is unreliable. You shouldn’t lose the data, not even in the event of a power outage.
    8. Additionally, in case of a power outage, you might prefer to get a separate critical alert. It goes without saying that this refrigerator power failure alert system should have a battery backup. If not, it won’t make a call alert in the event of a power outage.
    9. In the event of a power outage, data transmission will not take place. The data should be stored in the apparatus, though, and transmitted as soon as the power is restored. Even if your power supply is dependable, this feature will be helpful.
    10. SIM card-based phone call and SMS alert systems are available alongside cloud-based phone call alert systems. Even if there is a power outage, the SIM card-based alert system will continue to function. However, as soon as the power goes out, the cloud-based alert system will no longer work.
    11. You must, above all else, investigate the annual subscription fees. You might choose to purchase a system free of annual or monthly fees. There are systems available that don’t charge a yearly fee. However, such systems will also tack on SMS and call fees. You can assess a 5-year expense with annual charges while comparing various vendors.
    12. If you live in the US, you might need a system that complies with 21 CFR Part 11. According to their regional laws, this is not required in most other parts of the world. It goes without saying that 21 CFR Part 11 compliant refrigerator monitoring systems will be expensive.
    13. If it suits you better, look for a system that will routinely send you a weekly or monthly report of the data.
    14. Many monitoring systems keep records of temperature and humidity on their cloud-based platforms. Periodically, you can download the recorded data. You can find out how long the provider keeps this data on file. You might prefer to use their cloud system’s unlimited storage. As an alternative, you ought to be able to routinely download the data to your local server.
    15. The sampling interval, or frequency of data recording, must also be checked. You might require a sampling interval of one to three minutes for a refrigerator containing very sensitive items. You might choose a sampling interval of 5 to 10 minutes for a refrigerator stocked with typical items, though. You must determine whether you can program a sampling interval starting at 30 seconds before choosing a system.
    16. Before creating an alert, you should be able to program a delay timer. This is crucial for a refrigerator because the door will be opened frequently. Imagine a refrigerator with a temperature range of 2 to 8 degrees Celsius. You can set the system up so that it won’t alert you until five minutes have passed after the temperature has risen above eight degrees Celsius. Otherwise, you’ll get lots of false alarms.
    17. Do you demand that the system make a phone call if the door remains open for an extended period? Such features are present in some monitoring systems.
    18. Additionally, you need to review your organization’s data policy. Some businesses do not want to connect their servers to the cloud. They demand that all data and software reside solely on their own server. Most systems are unable to offer the same. Such a policy has been observed, particularly for very large organizations like hospitals, airlines, etc.
    19. There are monitoring systems for refrigerators with and without a screen. This is something you can choose based on your needs. The price of devices with displays will be higher than those without.
    20. You might have noticed that a single system might not be able to satisfy all the demands. As a result, choosing your priorities will help you choose the right answer.

Please confirm the number of operators who will receive the alerts. You might prefer that different operators receive the alerts for various refrigerators. For instance, one operator might oversee the refrigerators in one room, while another operator might be in charge of the ones on another floor. Keep an eye out for features like that.

We have various solutions that satisfy the various requirements listed above. We will help you choose the appropriate system. Send your inquiry to our central sales department, and a representative from your local office will get in touch with you to arrange a free consultation.
