USB Datalogging ULT freezer thermometer that can be used in 21 CFR 11 environments raw data is locked and may not be cleared/changed on base unit.

• Meets current CDC requirements for vaccine storage and monitoring
• Rolling memory structure, maintains most recent one million (1,048,576) temperature observations
• Smart-Alarm™ features a visual/audible alarm that continues to alarm even if the unit returns to non-alarm conditions
• Stores up to ten unique alarm events
• Memory can be cleared on unit after downloading data to USB stick
• Hassle-free retrieval of data - unit can remain in use while downloading and analyzing data
• Status indicators - Low battery, memory full, USB data transfer and active alarm state

Hi/Lo alarms and time/date stamps has feature stores in memory each alarm event detailing when the alarm state occurred, as well as when the unit returned back to within range. Alarm state indicators include visual LEDs, audio alerts, and flashing LCD segments. Data for up to ten different alarm events can be retrieved with the most current event viewable on the display.

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.

New feature allows recorded data (CSV file) to be transferred from thermometer to PC or Mac using a USB flash drive (not included). No software is needed for computer interface. Each thermometer has a unique ID allowing multiple units to be used in the same location.
Datalogging features has 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 a year of recorded data when using 1 minute intervals and longer when using larger intervals.

Highly accurate and reliable. Ideal for monitoring temperatures in refrigerators, freezers, water baths, heating blocks, and incubators. Device will stop recording when storage is full and will not overwrite recorded data. Data is unable to be deleted from memory once stored. Raw data on unit cannot be overwritten or modified. Indicator light will appear when 95% of memory is full. Temperature probe dimensions has 0.817"Ø×6" long and it has a cable length of 10' with calibration points of −80, −40, 0, 100 °C. It has A/C plug, exported data.
