Use our Ethernet enabled EDL-Net data loggers to enjoy real-time temperature and humidity data collection and monitoring at anytime, from anywhere in the world over a local network or via an internet connection. Leverage your existing LAN with the built-in RJ-45 jack for CAT-5 LAN, or an Ethernet-to-WiFi bridge for WiFi connectivity to avoid expensive installation costs for managing temperature data. Marathon’s Ethernet enabled loggers will allow you to monitor multiple floors, buildings, rooms and locations simultaneously.

Our advanced software can be programmed by the user to detect high and low temperature excursions, or power outages, and trigger audible and visible alarms as well as send alert notifications via cell phone and/or e-mail for facilities management control. Marathon’s 21 CFR: Part 11 compliant software, with secure supervisory controls, will allow database creations for products, part numbers, dates, locations, identification numbers, statistical
analysis, and more.

In the lab, our NIST-calibrated and traceable thermistor probes have been tested sterile and can be used in incubators. In hospitals, clinics, pharmacies and blood banks, the EDL-Net is perfect for quality assurance and quality control, monitoring low temperature freezers, blood storage, vaccines and biologics via state-of-the-art high-performance temperature sensors and data logging.

Note: Actual performance of the edl-RF system varies in each environment. Marathon strongly recommends the evaluation of the product in the actual environment of the application. Marathon publishes specifications typically experienced by our customer instead of publishing theoretical performance characteristics.

MDAS-Pro Software

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.
