• Your samples are precious and every precaution has to be taken to
PROtect their integrity. In case of a severe failure, the Esco PROtect
wireless monitoring system can monitor your freezer or other cold
storage system to make sure your samples are maintained at the
correct temperature
The monitored cold storage device communicates to the central
monitoring computer by radio frequency transmission allowing for
long communication distances and extended battery life
When a monitored device reaches a temperature alert, a loud audible
and visual alarm can be sounded as well as sending an email alert.
Multiple installations in remote buildings can be monitored and
multiple users can access the system simultaneously.

• A backup system keeps your samples at desired temperatures when the refrigeration system cannot.
Simply supply the backup system with an adequate CO

when power fails
• No ULT system that stores critical samples should be without a CO

• Protecting your samples during a power failure can be a challenge. In conjunction with a CO

or LN

backup
system and a large backup gas supply your ULT system must have an adequate supply of battery power to
last for the duration of the power interruption.
• Unfortunately most ordinary ULT system have a backup battery that will only last 8 to 24 hours. Insufcient
for many situations. The new Esco Lexicon® II ULT with the Aalto Platinum controller can be equipped with
a backup battery that will last at least 72 hours! Your samples deserve the best protection.
