The 3C\TEMP-USB -200C is a reliable and cost-effective digital temperature recorder for all industrial and commercial applications. It has one sensor for ambient temperatures inside the case, and one external RTD stainless-steel probe that monitors temperatures from -200°C (-328°F) up to +72°C (+161.6°F). It is ideal for monitoring all of your cryogenically stored stem cells and biologic materials. These high-precision laboratory-grade products will operate up to 1.5 years without a battery change. The LCD display provides real time viewing of ambient and probe temperatures prior to downloading to a computer.


  • Internal Thermistor: accurately records time and temperatures for user selectable readings in C or F.
  • LCD display: Real-time viewing of Current temperature, Max /Min Temperature, Run Time, Alarm Status, and Recording.
  • 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 - The data loggers can be programmed with alarm limits. Should the temperature reach levels outside these limits, the LDC (change to LCD) 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 available separately
  • The dataloggers are NIST-Traceable and come with Certificates of Conformance.
