LS3000 Cryo-Sentry Low Level Alarm
The LS3000 Cryo-Sentry Low Level Alarm passively monitors liquid levels in the LS3000 cryogenic refrigerator.
Used to protect valuable biological samples, this alarm will sound promptly to alert you when more liquid nitrogen is needed. Alarm includes remote alarm plug, which can be attached to a dialer/maintenance system to advise of an alarm when the lab is unattended. It is best suited for the infrequently used freezers and is recommended for stored product protection. Battery operated or powered by standard US grounded plug.
