Single-use Temperature & Humidity Logger with Real-Time LCD Display for Instant Acceptance or Quarantine Decisions.

This revolutionary, single-use, pre-programmed, electronic temperature data recorder is specifically designed for measuring temperatures during the transportation of refrigerated vaccines, biological material, chemicals, pharmaceuticals, and for documenting the transportation of perishable commodities. They are NIST-Traceable and come with Certificates of Calibration.

Functions include:

  • Internal Thermistor: accurately records time and temperatures for pre-set readings in Celsius or Fahrenheit.
  • LCD display: Real-time viewing of Current temperature, Max/Min Temperature, Run Time, Alarm Status, and Recording Status.

Small Form Factor:

These units have an extended battery life and can endure rough handling. The internal software records the following: time mechanism, start time, sampling 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 LDC will display “ALARM.” To start the recorder, simply press the start button!

Computer Ready:

Marathon’s easy-to-use MaxiThermal2 software is available for Microsoft Windows XP, 7, 8, 8.1 & 10. Simply plug the unit into a standard USB port on your PC. The Maxi-Thermal2 software and USB cable are required accessories and are sold separately.

MaxiThermal2 Software for USB Loggers

Marathon’s MaxiThermal2 Software for USB Data Loggers

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, as well as the ability to add a user note to the file for including information pertinent to that particular plot.
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.
