Your Best Protection

Whether you store vaccines your patients depend on, materials for laboratory experiments or other critical temperature inventory you need the TV2 Easy Freezer Alarm. 

The Easy Freezer Alarm protects any type of refrigerators and freezers, whatever make, model or temperature range.

The TV2 Easy Freezer Alarm automatically logs all temperature data so you can verify that your refrigerators and freezers have maintained safe temperatures.  And printing out a chart for the auditors or inspectors is simple.  The TV2 stores over 1.5 years of temperature history for each of the cold storage units being monitored if you are logging data once every 10 minutes.

More information

The free TView software is a powerful part of the TV2 alarm logger.  It runs on any PC or server to automatically backup the temperature log, in addition to downloading data on-demand.  TV2 plugged into a PC with the USB cable Nurse at deskIt can be used to view multiple TV2 on your computer.  So if you are using five TV2s to monitor twenty different freezers or refrigerators you could see all twenty temperatures and the recent history of each on your computer.

As long as the TV2 freezer alarm is communicating to your computer via USB or Ethernet connection an automatic download occurs, so that every few seconds the logged data is added to a file on your computer.


Quickly install on any Fridge and Freezer

1.  Place the sensors in the refrigerator and freezer.
2.  Set the date and time to activate the temperature logging.
3.  Set the high and low temperature for each sensor.
4.  Plug the USB cable into a computer or the wired Ethernet cable into your network.
5.  Install free software on a computer.
6.  Type in email addresses for email or text alerts. 

The Easy-Touch™ Display

The Easy-Touch™ display is used to set the alarm parameters, view theFridge freezer alarm current temperatures and  the temperature history log. 

The TV2 Easy-Touch screen is a stand-alone instrument powered via a USB cable, which can be plugged into a computer or a wall socket adaptor.  Its 72 hour internal lithium back-up battery immediately takes over the operation of the alarm if the power fails. 

The screen is normally placed near the refrigerator and freezer being monitored but can be mounted on the wall 100 feet away.

Automatic temperature logging

The TV2 easy-touch display receives a temperature from the refrigerator and freezer sensors every few seconds.  It stores the average of all those temperatures every ten minutes, so there is no need to record the temperature manually. All temperatures are stored in non-volatile memory that can be automatically backed up to your computer every few seconds.  The easy-touch display stores years of temperature history for each refrigerator or freezer.

Documented Proof for Auditors and Regulators

The TV2 Freezer Alarm complies with the latest CDC, JCAHO, FDA and CAP requirements and recommendations that temperature of refrigerators and freezers be logged.  Each chart can be digitally signed and dated to comply with the 21 CFR 11 requirements. 


Sensors

Wired Sensors

Sensor plugged into the TV2Each wired sensor (±0.3°C) comes with a twenty-foot wire that plugs into the Easy-TouchDigital temperature sensor Display.  Wire extensions are available so the sensor can be positioned as much as 200 feet away from the display.  TV2 digital sensors remain in calibration for years and can be calibrated to NIST standards. Recalibration can be done by metrology labs or even at your location by comparing temperature to a certified and/or calibrated thermometer.  Each sensor has its own calibration table which is user accessible.

Wireless sensors

Each wireless sensor uses a high accuracy thermistor (±0.3°C) with a transmitter that broadcasts the temperature to the TV2 display.  The transmitterBacklit display is normally placed on the outside of the refrigerator or freezer and the sensor wire is snaked into the cold compartment over the gasket on the hinge side.  The sensor should be positioned within 40 feet of the display to ensure the transmitted temperatures are received. Wire extensions are available to extend the two-foot wire to the sensor.
