c\temp-Gen2 is the revolutionary single-use pre-programmed electronic temperature recorder developed by Marathon Products. It is specifically designed for measuring temperatures during the transportation of refrigerated vaccines, biological material, chemicals, pharmaceuticals, and documenting the transportation of fruits and vegetables.

Functions include: The internal thermistor accurately records time and temperatures for user selectable readings in Celsius or Fahrenheit. The internal software records the following: time measurements, start time, intervals, end description for special instructions, alarm values, recording status, measurement data, software version, serial and tracking number, model type and after the fact report generation options.

Visual alarms: All our data loggers can be programmed with alarm limits. Should the temperature reach levels outside these limits, the onboard red LED will light until reset by the user. To start the recorder, simply press the START button!

Computer ready: MDAS is used to read the logger. It runs on Windows 2000, XP, Vista, 7 & 10.  To download recorded information,simply plug the unit into the standard USB port of your PC. The software is available as a separate accessory item.

c\temp Read-only Software

Centralized Monitoring

Our MDAS Read-only software is Read Only and it is not for programming. This is used to read data collected from our single-use data loggers. It has all the features of the MDAS-PRO, but excludes the ability to program the devices. If you have received one of our data loggers and need a copy mailed to you, please call 1-800-858-6872. Click this link to download the MDAS Software.
It features the ability to view up to 16 multiple traces at one time, 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 cable or USB interface.
The software 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.It has been designed for the Microsoft operating system platforms and is compatible with Windows XP, Vista and Windows 7, 8 and 10.
