Our edl Cloud RTD/LN2 wireless data loggers monitor high and liquid nitrogen temperature in a small compact package for stationary applications.
Warehouse, laboratories and refrigerators would be an ideal fit for these easily-installed, high-powered data loggers. Now store data in a central database or your cloud. Alerts and reports can be downloaded automatically and emailed.
The system uses a gateway or gateways that connect to your local LAN and or cloud. Our data loggers use low-powered Lora transceivers with long life batteries so that AC Adaptors are no longer required. All data is captured at pre-defined intervals and then stored on the local server or cloud platform for easy data retrieval and review. Now provide on demand mapping of your warehouses refrigerators and high-value biologics.
Three models are available to fit your needs. This system is scalable and easily upgradable. The same gateways can be used to leverage and provide continuous visualization of temperature and relativity humidity data.

MaxiThermal2 Software for USB Loggers

Marathon’s MaxiThermal2 Software for USB Data Loggers

Marathon’s MaxiThermal2 Software allows you to view up to 8 multiple traces at one time, enables you to transfer the recorded information in your loggers to your computer, and to view, print and generate a report of the measurement data. The graphic representations are a simple X – Y plot of time versus temperature with unlimited zoom. The graph and all data points (date, time and temperature) can be printed.

Users have the ability to view numeric data in a screen window and Data can be Exported as a CSV file for use in other software. A Summary Information report showing the specific logger information, the Start and Stop Time, Duration of Recording, Measurement Interval, Highest, Lowest, Median and Average Temperatures as well as the High and Low Alarm information.

The data from the logger is easily downloaded to your PC via a standard USB 1.1 interface. MaxiThermal2 software is compatible with Windows XP, Vista, 7, 8 and 10.

MaxiThermal2 Software is not 21CFR Part 11 compliant. Click here for 21CFR Part 11 Compliant Software.
