Liquid Nitrogen Level
Monitor Operation
The liquid nitrogen (LN2) level monitor provides a constant indication of
the LN2 level and notifies you to low level conditions through audible and
visual alarms. It alerts you when your vessel needs filling. The level
monitor is shipped mounted directly to the appropriate Locator or Locator
Plus cover. It can be wired to a remote alarm system to alert you to
problems when you are not in your laboratory. This equipment was
intended to be operated with an external power supply provided by the
manufacturer. It is designed for use with Thermo Scientific LN2 vessels
only.
