Stand up refrigeratorThis alarm is simple to install and use

Having one instrument that does all of this begs the question: "How hard is this thing to install and use?" 

Installing the Easy Freezer Alarm in 4 simple steps

  1. 1. Put a battery into each wireless sensor.
  2. 2. Position the  sensors.
  3. 3. Plug in the TV2 to the wall or a PC.
  4. 4. Review the date & time and set the alarms.

    1.             That is it.  You are done.

Monitor four places simultaneously

The TV2 Easy Freezer Alarm receives and displays temperature and humidity data from four sensors. Whether the sensors are sending temperatures from refrigerators, freezers, incubators, or temperature and humidity from operating rooms the current condition(s) is displayed on the 'Current Status' screen and on the individual charts.  The maximum and minimum temperature is also displayed along with the battery level of each senor if the senor is wirelessly transmitting to the monitor.  The maximum and minimum temperature can be reset or 'zeroed out' by touching the display so that it begins again.  This is useful if the user needs to periodically manually record the maximum and minimum temperature.

The TV2 also indicates the condition of each refrigerator or freezer. Sensor #1 with unsafe temperature The current temperature along with the maximum and minimum temperature appear in green as long as the temperature is within the safe range.  However, if the temperature moves above the high alarm point it immediately turns red.  Once the temperature moves back into the safe zone it again turns green, except for the maximum temperature which stays red until it is reset.  Because the color of the temperature reflects the conditions of the refrigerator It only takes a quick glance at the display to see if the temperature is safe or not.

Since a delay can be set for the actual high and low temperature alarms it is possible for a temperature to appear red, indicating it is outside the safe zone, without an alarm being triggered.  So a temperature that gets too warm and then cools off before the delay time elapses would show as red and then green, but no alarm would sound.

The sensor battery indication on the display will turn red if the battery voltage drops below 20% to alert the user to the need to replace it.

Text, email or phone-call alert on alarm. Ringing alarm

The TV2 Easy Freezer Alarm has an external normally open (N/O), dry contact relay, to trigger a phone call when an alarm occurs.  The optional Auto Dialer calls several phone numbers to deliver or leave a message if an alarm occurs.    The external relay connection can also be wired into a building alarm system or used to trigger a powered external alarm.ringing cell phone

The Easy Freezer Alarm can also send an email or text alert when an alarm occurs if the TV2 Easy Freezer Alarm is plugged into a computer or the Local Area Network and you are using our PC interface software, TView, with email option.

The free TView software is a powerful additiaon to the Freezer Alarm.  It runs on your PC and can be used to automatically copy the temperatures, in addition to downloading data on-demand, to ensure that you will always have a backup of your temperature history.  TV2 plugged into a PC with the USB cableNurse at desk

TView can show the current temperatures of multiple Easy Freezer Alarms on your computer.  So if you are using five Easy Freezer alarms to monitor twenty different refrigerators you could see a temperature chart of each refrigerator on your computer.  The temperature chart would show the last 100 saved temperature readings along with the current temperature.  And should an alarm occur, the temperature chart immediately turns red.

Our optional Email software will send an email or text message when an alarm occurs as long as the Easy Freezer Alarm is talking to your computer.  The USB power/interface cable can be plugged into any USB port on your computer.  Once the connection between your computer and the TV2 has been established an automatic download can be started so that every few seconds the collected data stored in the TV2 will be copied onto your computer.  This automatic backup can be accessed at any time to view the temperature history or print out charts for audits.

Your Secret Weapon for Complete Protection

Whether you are protecting vaccines your patients depend on, laboratory experiments in process, priceless art treasures, or airplane wings stored at a constant temperature and humidity the TV2 Easy Freezer Alarm ensures all is well. 

If you are storing tissue samples or human embryos in a -80 freezer you can sleep easy at night knowing that the TV2 Easy Freezer Alarm is on the job.  If the temperature in a refrigerator or freezer gets too high or low it will notify you either with a phone call, email or text so you can move the product to a safe location.

The TV2 Easy Freezer Alarm keeps a log of all the temperatures so you can verify that your refrigerators and freezers have maintained a safe temperature.  And printing out a chart for the auditors or inspectors is simple.  The TV2 Easy Freezer Alarms stores over 1.5 years of temperature history for each of the cold storage units being monitored.  All of that stored history can be copied over to your PC with the free TView software.

More information


The TV2 Easy Freezer Alarm, has a number of alarms which have to do with the TV2 itself, and additional alarms for the sensors or the conditions being monitored by the sensors.  All alarms are indicated visually on the TV2 with a message, a blinking screen and in some cases will cause an area of the screen to turn red.  Some alarms are logged in the TV2 non-volatile memory and in files stored on your PC.  Additionally if the TV2 is plugged into a USB port on a PC at the time an alarm occurs it will be indicated on the PC in real time.

All temperature and humidity alarms cause the external normally-open (N/O) dry-contact relay to close.  This can be used to trigger an auto dialer so that phone calls are made to alert the staff that an unsafe condition has occurred.  Alarms can also initiate a Text or Email message.

Sensor condition alarms

  • High temperature alarm - buzzer, flashing message, closes relay, logged to memory
  • Low temperature alarm -buzzer, flashing message, closes relay, logged in memory
  • High humidity alarm -buzzer, flashing message, closes relay, logged in memory
  • Low humidity alarm -buzzer, flashing message, closes relay, logged in memory
  • Low sensor battery - battery indicator flashes red and icon show a low percentage reading
  • Temperature outside high or low set points - displayed temperature reading turns red, max or min conditions turns red
  • Humidity outside high or low set points - displayed humidity reading turns red

How safe is your data?

Your temperature data is stored in non-volatile memory so even if you turn the Easy Freezer Alarm off and come back 10 years later all of your data will still be there. 

During power outages the rechargeable internal batteries (Lithium Ion) will continue to operate the TV2 for up to 72 hours.  And by operate we mean everything continues to work as if it was not operating on batteries:

  1. Data logging continues
  2. Alarms will sound, show on the display and be recorded
  3. The relay will close if an alarm occurs
  4. Phone calls and/or emails will be made or sent.
  5. Data can be copied to your computer.

Each TV2 Easy Freezer Alarm monitors four different areas.Current Status area for one sensor

Since the TV2 Easy Freezer Alarm can track four different temperatures and humidity readings simultaneously you only need one display for four sensors.  This lowers the cost of monitoring multiple areas and means that you only have to look at one display to see what the current conditions are each area.  The picture at the right is one fourth of the current status display showing the current conditions for one of the sensors and the maximum and minimum temperature recorded.  The current battery charge for the sensor is also displayed. 

TV2 chart displayIn addition to the current status display you can also view the historical conditions for each area.  The TV2 Easy Freezer Alarm has an 'Easy Touch' display  for simple operation.  To look at detailed information for one of the sensors you simply touch that temperature.

With one touch on the display a temperature chart immediately opens up so you can see what happened last night, last week, last month or even last year.  To see additional temperature history just touch the display again and scroll bars will appear on the chart.  The chart can be scrolled to the left or right to show earlier data.  It can also be zoomed into or out of to show much more historical information.  The chart is not only paperless it is never ending.  Once all of the non-volatile memory is filled with data the newer data will roll over oldest data, so you will always have the last 80,000 measurements stored for each sensor. 

Being able to see the temperature history makes it easy to spot trends.  This is particularly useful for troubleshooting issues with refrigerators, freezers or areas in a warehouse or building.

All Logged Temperature Date is Encrypted to Comply with 21 CFR 11 Requirements

Once the temperature and/or humidity data is collected from the sensors it is stored in the non-volatile memory of the TV2 Easy Freezer Alarm. It is impossible for the user to change the data once this happens.  It can only be viewed not changed.

Logged data can be downloaded with the TView software so that it can be seen on a PC and even saved as a file but as it is saved it is encrypted with a 256 bit encryption algorithm. And once this happens it can only be viewed and/or printed out as a chart.  If a user name and password have been entered and a saved chart is opened with the TView software a small 'padlock' icon is displayed indicated that the file has been signed.  A signed file can only be opened if the same username and password are entered.

Likewise if a chart is printed out from TView a 'signature verified' or 'signature unverified' text box will appear at the top of the printed chart.  This procedure ensures that 21 CFR 11 is complied with.

The data can also be exported in unencrypted form to Excel where it can be viewed and manipulated if the user wants to analyze it.  In this case the data is not encrypted and no padlock or verification indication is shown.  The padlock and verification pen only appears on printouts or on a computer screen if the data integrity has been maintained.  This is comply with various regulations, such as 21 CFR 11.
