Product catalog summary
Liquid Nitrogen Level Measurement
The system uses differential pressure to measure LN2 levels with an accuracy of ±0.5 inches and a resolution of 0.1 inches. It features a single-point calibration over a range of 3.0 to 48.0 inches, displaying measurements in inches, millimeters, or percentage full.

Automatic Liquid Nitrogen Level Control
This automated system allows user-defined parameters for LN2 level control, including alarms and fill points. It includes redundant dual solenoid valves for overfill protection, operating at 24 VDC, 1.0 amp.

Liquid Usage Monitoring
The system estimates liquid usage to track LN2 consumption and provides early failure warnings to protect samples.

User-Defined Alarms
There are audio/visual alarms for various conditions such as temperature extremes, liquid usage, fill time, and more.

Remote Alarm Monitoring
Global remote alarm relay features allow precise monitoring and control of freezer environments.

Temperature Measurement
Two independent channels with platinum RTD sensors measure temperature with ±1.0°C accuracy and 0.1°C resolution, including altitude compensation.

Hot Gas Bypass
This feature vents warm nitrogen gas before filling to maintain temperature stability and reduce LN2 evaporation.

Event Log/Data Storage
The system stores up to 30,000 events in nonvolatile memory, including time-stamped data on temperatures, LN2 levels, and alarms.

Password Security
A multilevel security system with up to ten programmable passwords and four security levels controls access to settings.

Communication Capabilities
An independent port allows communication with other devices and networks using protocols like ASCII and MODBUS.

Contact Information
Chart BioMedical provides contact details for various regions, including the USA, Europe, Japan, and Australia.
