Covering cryogenic needs for sensitive, irreplaceable biological samples.

• Liquid nitrogen USB datalogging thermometers that can be used in 21 CFR 11 environments
• Memory capacity of 525500 temperature observations
• Four calibration points (–196, –80, 0, and 100 °C)
• Recorded data (CSV file) may be transferred from base unit to PC or Mac using a USB flash drive, with no additional software needed
• Smart-Alarm™ features a visual/audible alarm that continues to alarm even if unit returns to non-alarm conditions
• Monitors readings for any period of time
• Status indicators: low battery, data downloading status, flashing LCD symbols, and audio alarm indicating active alarms

Hi/Lo alarms and time/date stamps: Alarm tracking feature stores in memory each alarm event detailing when the alarm state occurred, as well as when the unit returned back to within range.

Smart-Alarm™ Signals out-of-range conditions: When an out-of-range condition is sensed, the Smart-Alarm™ triggers. Smart-Alarm™ features visual and audible indicators which signal continuously until acknowledged, even if the parameter returns to the non-alarm range.

USB data transfer: This liquid nitrogen temperature monitor allows recorded data, in a CSV format, to be transferred from the thermometer to PC/Mac with a USB flash drive (not included). Specific software is not needed for this thermometer and data can be deleted from memory. Each device has a unique ID that allows multiple units to be used in the same location. This device can be used by organizations that must adhere to distribution adhering to USP 1083, and it is especially useful for transportation monitoring.

Datalogging features: Monitor readings overnight, on weekends, or for any time period with rolling data log. User-defined datalogging interval of one observation/minute to one observation/24 hours. Memory capacity maintains 2 years of recorded data when using 1 minute intervals and longer when using larger intervals.

Alarm state indicators include visual LEDs, audio alerts, and flashing LCD segments. Data for up to 10 different alarm events can be retrieved with the most current event viewable on the display. High accurate and reliable. Indicator light will appear when memory is 95%. Unable to delete data from memory once stored. Allows user-defined logging interval from every minute to every 24 hours. Over one million temperature observations.
