• 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

gas supply and your samples will be protected
when power fails
• No ULT system that stores critical samples should be without a CO

backup system.
• 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. Insufcient
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.
