Once you enter in your safe zone for each freezer the TV2 checks every four seconds to see it the temperature has become unsafe. An alarm delay is usually set to eliminate false alarms caused by the door being opened or warm product loaded into the freezer. So if the temperature gets too warm for too long, or the power fails, the freezer alarm goes into alarm mode upi are alerted. the TV2 alarm can even send all three alerts; text to multiple phones, emails to several people and phone calls to additional people.
It is all too easy for a freezer to malfunction by warming up and then cooling down while no one is around. This sometimes happens when the compressor relay gets stuck. Should that happen it would not be noticed if the temperature was being recorded once or twice a day, but the TV2 will catch it every time.
With the TV2 Freezer Alarm you immediately know if the temperature became unsafe when no one was around. The freezer temperature history is one-touch away, so one glance tells you all you need to know about what happened last night or last month or even last year..
The TV2 Freezer Alarm is used in health clinics, pediatricians offices, labs, hospitals, manufacturing plants, and even commercial kitchens to alarm and document freezer and refrigerator temperatures.
You can view a temperature chart on the TV2 Freezer Alarm. The chart is so easy to understand that each member of your staff will "get" it without any special training. They automatically become part of your quality control system every time they glance at the display. Anyone can immediately see if everything is OK or if something happened while no one was looking. If all the numbers are green everything is OK. If a number is red there is a problem.
One glance at the display shows that freezer number 4 is too warm. Once it cools down the -5.0°temperature will turn green. To see how long it has been unsafe touch the -5.0°reading and the screen will change to show a temperature history chart.
The TV2 Freezer Alarm complies with all CDC, JCAHO and CAP requirements. It displays and prints charts or temperature lists for regulators or auditors as proof that your inventory has been properly stored and maintained.
All logged data is stored in encrypted format and can be electronically signed. All downloaded files are encrypted with 128 bit encryption. Once the data has been logged to the Freezer Alarm it can never be changed, even after being downloaded to a computer as long as they are stored in the TV2 format. Of course, if they are imported into Excel the encryption is broken.

NIST traceable calibrated sensors are available. Recalibration can be done by metrology labs or even at your location by comparing the temperature to a certified and/or calibrated instrument. Each sensor has its own three point calibration table which is user accessible.
The TV2 Freezer Alarm is powered via the USB cable plugged into a wall-power plug or a PC. If power is interrupted, the internal batteries take over and continue to run the unit for up to 100 hours. All monitoring and logging and even alarms will continue to operate normally while running on battery. The display goes to sleep to preserve the battery but this does not affect the collection of data or alarms. Batteries are automatically recharged when power is restored.
There are no monthly fees. You own this TV2 Freezer Alarm and dialer. You decide when and who the auto dialer calls to deliver your sixteen-second prerecorded message, if you are using the optional auto dialer. The TV2 is completely stand alone and will operate without a computer. No one has to check on it every month. It uses no paper charts or pens and requires no maintenance - there are no moving parts to wear out or replace.
The TV2 freezer alarm is simple to install and use. Begin by placing each sensor into the freezer you want to monitor. The sensor can be positioned in the freezer or placed in a bottle of glycol. the sensors are fully immersible. After positioning the sensors, supply power to the display. The Setup menu will appear so you can set the date, time and sample interval. The TV2 Freezer Alarm immediately begins to collect, log and chart temperatures. Lastly set your alarm parameters.
