LNDS
Product Information Card
Product Notes
The LNDS is a liquid nitrogen monitoring and data logging system. The thermocouple can be
placed into the liquid nitrogen tank with the lid closed upon it. Verify the thermocouple probe is
sealed by the gasket on the lid.
A type E thermocouple is supplied with the system and is recommended for use with the LNDS.
The convenient LCD provides access to the current temperature, as well as minimum, maximum
and average statistics.
Backlight
The backlight uses a significant amount of battery life. Refer to the manual to configure the auto
shut-off when not in use.

Device Operation
Connecting and Starting the data logger
- Once the software is installed and running, plug the interface cable into the data logger.
- Connect the USB end of the interface cable into an open USB port on the computer.
- The device will appear in the Connected Devices list, highlight the desired data logger.
- For most applications, select “Custom Start” from the menu bar and choose the desired
start method, reading rate and other parameters appropriate for the data logging
application and click “Start”. (“Quick Start” applies the most recent custom start options,
“Batch Start” is used for managing multiple loggers at once, “Real Time Start” stores the
dataset as it records while connected to the logger.)
- The status of the device will change to “Running”, “Waiting to Start” or “Waiting to
Manual Start”, depending upon your start method.
- Disconnect the data logger from the interface cable and place it in the environment to
measure.
Note: The device will stop recording data when the end of memory is reached or the device is stopped. At this
point the device cannot be restarted until it has been re-armed by the computer.
Downloading data from a data logger
- Connect the logger to the interface cable.
- Highlight the data logger in the Connected Devices list. Click “Stop” on the menu bar.
- Once the data logger is stopped, with the logger highlighted, click “Download”. You will
be prompted to name your report.
- Downloading will offload and save all the recorded data to the PC.
Device Maintenance
Battery Replacement
Materials: 3/32” HEX Driver (Allen Key), Replacement Battery (U9VL-J)
- Remove the back cover from the device by unscrewing the four screws.
- Remove the battery from its compartment and unsnap it from the connector.
- Snap the new battery into the terminals and verify it is secure.
- Replace the cover taking care not to pinch the wires. Screw the enclosure back together securely.
Note: Be sure not to over tighten the screws or strip the threads.
Recalibration
