Optional Features
Overow Sensor: (Not included as standard equipment, can be purchased separately)
This feature uses a thermistor set at the bottom of the storage space along the probe holder tube. If an overow
occurs it will cause the LN2 to make contact with the thermistor. An audible and visual alarm will occur and
“SYSTEM STATUS: ALARM ** LN2 OVERFLOW **” will appear on the display and power to all solenoid valves will be
disabled.
NOTE: Turbulence from liquid nitrogen supply may trip alarm if operated at higher levels than factory set points
(Low: 10” High: 17”).
