The MM120 is a simple, cost effective temperature monitoring tool. The MM120 does not track your data, but it is a useful backup to a traditional data logger in your vaccine or drug monitoring application.

  • Tamper-resistant audible/visual alarms
  • Thermistor probe submersed in glass bead solution for stabilized readings
  • Tracks Min/Max Temperatures
  • Easy to read display

We recommend using the MM120 and MM125 as backup devices to data loggers that record temperature values over time. The FDA and CDC specifically recommend using data loggers with alarms to monitor vaccine storage.

NOTE: The MM120 now comes with the temperature sensor submersed in glass beads instead of a Glycol solution. Both glass beads and Glycol are recommended by the CDC for vaccine (including VFC) storage. If you have any questions about this, feel free to contact us.
