microDL-80°C Digital Display Temperature Logger
Record and Log Ultra-low Temperatures in Shipments, Refrigerators or Freezers. The compact, coin-sized microDL-80°C is the industry standard for monitoring dry ice temperatures.
Available Memory Sizes: 8k, 32k or 64k.
Temperature Range: -80°C to +30°C
Description
The multi-use microDL-80°C digital display technology operates at ultra-low temperatures of -80°C (-112°F). The compact, coin-sized unit with the external thermistor probe can now help you verify that internal temperatures of your dry ice packages meet specifications prior to acceptance of your shipment. Simply push the start button to view critical temperature information upon arrivals. With optional memory sizes of 8k, 32k and 64k, and a one meter long flexible ribbon probe this product is the answer for data logging ultra-low temperature freezers or dry ice shipments. Custom configurations are available, just ask.
Flexible: Pressing the button will display the following visual information, whether or not the logger is recording: Current Temperature, Elapsed Time in Days, MKT (Mean Kinetic Temperature), High Temperature, Low Temperature, Alarm Time Over High Temperature, Alarm Time Below Low Temperature, and Alarm Conditions.
Customizable settings include: Delay to Start, Stop, Elapsed Time as well as customizable sampling time intervals. Also available: User Descriptions for initialization and for downloading the data.
Visual Alarms: All our data loggers have the ability to program alarm limits. Should the temperature reach levels outside these limits, the digital display will show a notice until reset by the user. Alarm conditions can be programmed for start/delay, high/low, continuous or cumulative time over alarm. Push the start button to view critical temperature information anytime.
Computer Ready: You can download the recording to your PC and plot the data, at any time. Our proprietary microDL USB Reader is needed to download temperature information to a computer. Marathon’s easy-to-use MDAS-Pro software is available for PCs running Microsoft Windows XP, Vista, and 7, 8 & 10. 21CFR compliant software is available with full database capabilities.

Centralized Monitoring:
Our MDAS-Pro software is the ideal solution for managing and analyzing data from multiple data loggers from multiple locations. With IP Address access MDAS-Pro is location independent so data loggers located anywhere can be centrally monitored and managed.
Marathon’s Data Analysis Software (MDAS) allows you to view up to 16 multiple traces at one time, enables you to transfer the information recorded in the logger to your computer, and to view, print and generate a report of the measurement data. The graphic representations include rotating 3D views, unlimited zooms, view temperature data points on the graph, view the total elapsed time or the exact time when it was recorded.
The graph and all data points (date, time and temperature) can be printed, as well as the ability to add a Note to the file for including information pertinent to that graphic trace. Users have the ability to view the numeric data within a screen window, calculate the Mean Kinetic Temperature of the recording as well as export data in a CSV format. A summary report showing the Start and Stop Time, High, Low, Median and Average temperatures as well as the Alarm information is also displayed. The data from the logger is downloaded to your PC via our proprietary RS232 serial interface cable or USB interface.
MDAS-Pro offers language support for English, French, German, Portuguese and Spanish. A separate installation program for Chinese and Japanese is also available on the CD-ROM with this version of the software. The software has been designed for the Microsoft operating system platforms and is compatible with Windows XP, Vista, 7, 8 and 10.
