    Product Information



    Traceable® Memory-Loc™ USB Datalogging Refrigerator/Freezer Thermometer
    Featuring 1 sealed glycol-filled bottle probe

    Meets current CDC requirements and additional recommendations for vaccine storage and monitoring
    Use in 21 CFR 11 environments, raw data is locked and may not be cleared/changed on base unit
    Allows user-defined logging interval from one observation/minute to one observation/24 hours
    Smart-Alarm™ features a visual/audible alarm that continues to alarm even if the unit returns to non-alarm conditions
    Stores up to 10 unique alarm events
    Capable of storing over 1 million temperature observations
    Hassle-free retrieval of data - unit can remain in use while downloading and analyzing data
    Status indicators - Low battery, low memory, USB data transfer and active alarm state

    Hi/Lo Alarms and Time/Date Stamps

    Temperature alarm settings are user-defined. In the event of a temperature breach of an alarm setting, the memory will retain the alarm event along with date and time details as well as when the unit returned to within range. 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.

    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 transferring

    All 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. Raw data on unit cannot be overwritten or modified. Indicator light will appear when 95% of memory is full.

    Data-Logging Features

    Can be used in environments requiring 21 CFR 11 compliance. Allows user-defined logging interval from one observation/minute to one observation/24 hours; Maintains over 1 million temperature observations. Device will stop recording when storage is full and will not overwrite recorded data. Data is unable to be deleted from memory once stored.

    Highly accurate and reliable

    High-accuracy thermometer has a temperature range of –58 to 158°F (–50 to 70°C) and resolution of 0.01 and maintains an accuracy of ±0.25°C across the entire temperature range. Ideal for monitoring temperatures in refrigerators, freezers, water baths, heating blocks, and incubators.

    Bottle probe

    Bottle probes are sealed in a miniature bottle (1 x 2-1/2 inches) filled with nontoxic glycol. Solution is GRAS (generally recognized as safe) by the FDA (Food and Drug Administration). Eliminates concerns about incidental contact with food or drinking water. Temperature-buffered bottle sensor eliminates rapid changes when refrigerator door is opened. Ideal for use in monitoring storage conditions for vaccines or other important samples. Meets all current CDC requirements and recommendations for temperature monitoring of vaccine storage as part of the Vaccines for Children program.

    Traceable® Certificate

    Multi-point calibration on an individually-numbered Traceable® Certificate which assures accuracy from our ISO/IEC 17025:2005 (1750.01) calibration laboratory accredited by A2LA.  It indicates traceability of measurements to the SI units through NIST or other recognized national measurement institutes (NMI) that are signatories to the CIPM Mutual Recognition Agreement. High-impact, chemical-resistant ABS plastic case is 2-3/4 x 4-1/4 x 3/4 inches. Weight is 5 ounces. Supplied: probe, stand, Velcro®, magnetic strips, wall mount, Traceable® Certificate, and batteries. Replacement battery Cat. No. 1105.
