Freezers and refrigerators are very reliable and rarely fail.  But when they do fail, it can be very expensive and the consequences tragic.  Last week the CDC published a report on the Vaccines for Childrens Program, which showed that 76% of the studied providers had issues with stored vaccines where they were exposed to at least fove hours of dangerous temperatures during a two week period.  The fridges and freezers that were used to store the vaccines were not monitored for temperature and there was no way to tell if they were still viable.

A Freezer malfunction at Harvard hospital damaged 150 brains used to study autism, which has pushed research into Autism back 10 years.  The freezer failed three days ago and nobody knew about it.  It damaged over 150 brains used in many types of research.  

There is a simple solution to these issues.  If the pediatricians, health clinics, and research labs had installed our 2di Fridge-Freezer alarm and auto dialer on their fridges and freezers they would have received a phone call as soon as the failures occured.  The Fridge-Freezer alarm monitors the temperature and if the temperature gets too warm or too cold for too long, phone calls are made.   Each sensor has its own high and low alarm, with a programmable delay to prevent false alarms.

The ThermaViewer uses wired or wireless sensors to sense, store and display temperature and humidity on its graphic display. You can chart; refrigerators, freezers, ovens, rooms, display cases in museums, outside conditions, etc... And the interior alarm will begin beeping anytime the temperature gets too warm or cold according to your settings.

The chart on the LCD display continues to grow as you sample the temperature just like the old-fashioned chart recorders. You can scroll through the temperatures and even zoom out to see more information at one time. In fact, you can zoom out to see over a year of temperature history. The ThermaViewer can be used with a wide range of sensors so you can monitor temperatures in the cryogenic range as easily as the melting point of lead. If you sample temperature every 10 minutes you can literally see more than 1.5 years of temperature history on the screen at once.

And of course all the data can be copied to a computer for printing or archiving.  Your data will display as a chart on your computer, which you can print out or save.  Saved data is always saved as an encrypted file.  You can also export the data to an XLS file for use in Excel.

They are used by Health Clinics, National Guard units and even Aircraft manufacturers to ensure the safety of their inventory stored in refrigerators and freezers.

The unique aspect of this alarm is that everyone can see the temperature history right on the face of the instrument.

A customer recently told us that the fellow who mops the floor at night in a nursing home left a note saying that someone should look at the freezer because the chart looked a 'little different'. When maintenance looked at the chart, sure enough, it showed that the temperature was a couple of degrees colder than normal. Consequently he checked the freezer and found the condenser was iced up, indicating a possible compressor problem.   If the compressor had failed, not only would the compressor have had to be replaced but all of the food stored in the freezer would have thawed out and would have had to be replaced also.  Thanks to the note left by the cleanup crew, a very expensive incident was avoided because the 2di Fridge Freezer Alarm chart was visible to everyone.

The auto dialer would have called someone when the temperature began to warm up after the compressor failed, but by catching it when he did he saved the nursing home a lot of money.  The chart showing the temperature history shows every little deviation making it possible to check on the health of the fridge or freezer at any time.

Data can be downloaded on-demand or continuously from a 2di Fridge-Freezer Alarm to a computer through the serial port on the alarm.   Our free software, which comes with the alarm can be installed on your computer and the alarmr plugged into the computer with a serial or USB cable supplied. Once you have specified which port the alarm is on with the Setup tab of the software, just click on the Download button.  Your data will be copied as a chart to your computer.

You can download one or more sensors simultaneously, each one drawing its own chart on your monitor in a different color. From there it can be printed, moved, deleted or saved to a file.  Data saved to a file can be viewed in our software or in Excel or another program which reads CSV files.  Of course, every time a file is saved an encrypted version ot the file is saved also to comply iwth 21 CFR 11 requirements.

If you want to see real time data on your computer, there is an auto download function and a current view screen which can be used to constantly copy the logged data to your computer.

And lastly there is a setting where you can see live data, updated every few seconds.
