Vaccine Alarm Thermometer

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.

Why should I calibrate?

All instruments lose accuracy over time due to normal usage and the environmental conditions to which they are exposed.

How often should I calibrate?

For most applications, the recommended calibration interval is every twelve months.

What is NIST Calibration?

NIST stands for the National Institute for Standards and Technology. This organization is responsible for maintaining the master for different measurements, such as the standard "foot", standard, "second", or standard "pound". NIST also maintains the standard for temperature, humidity and pressure.

NIST Traceable means that the measuring standard can be traced directly back to the master standard maintained by the NIST organization.

NIST-Traceable does not tell you the measurement accuracy of a metrologty service in any detail. Only metrology services that can document their ISO 17025 standard provided data on their best measurement uncertainty.
