The 2c\temp is our entry level data logger that offers the best value against all competition. You won’t find a better product with these features. This multi-use data logger is a low-cost and effective solution for temperature monitoring of refrigerated vaccines, biological material, chemicals, pharmaceuticals and documenting the transportation of fruits and vegetables. It boasts a convenient palm-sized design. The internal thermistor accurately records time and temperatures for user-selectable readings in Celsius, Fahrenheit and Kelvin.

Flexible: The internal firmware is user programmable and provides the following features: start time delay, sampling intervals, high and low alarm values, recording status, and measurement data. Operation is as easy as pressing the Start button on the recorder.

Visual Alarm: All our data loggers have the ability to program alarm limits. Should the temperature reach levels outside these limits, the on-board red LED will light until reset by the user.

Computer Ready: After recording, simply download all of its data to your PC with a compatible serial cable and Marathon’s easy-to-use MDAS-Pro or 21 CFR software. Compatible with Microsoft Windows XP, Vista and 7, 8 & 10. 21CFR compliant software is available with full database capabilities. We also offer a USB to Serial Port adapter. Software and cables sold separately (see Software and Accessories tabs).

Centralized Monitoring:

MDAS-Pro Software

Our MDAS-Pro (Marathon’s Data Analysis) Software is a desktop application that 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 interface cable or USB interface.
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 with network access, located anywhere, can be centrally monitored and managed.
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.
