The MT300 EX module monitors two individual temperature sensors and also records the minimum and maximum temperatures of each sensor. You can use the MT300 EX on-board when used with a Duplex receiver, Duplex Expander or hand-held when connected directly to a JetiBox Profi. The MT300 EX allows you to set alarms to let you know if the temperature is either too high or too low than the user-defined settings for each sensor.

Through the Duplex 2.4GHz system and either a JetiBox Profi or Jeti Transmitter you can monitor both of the temperature sensors data and alarm conditions in real time.
