Dual Input Thermocouple Thermometer (Differential) - MM2020


This instrument is designed for applications requiring either direct or differential measurement. It incorporates many features such as:

  • *C / *F / *A Switchable
  • True arithmetic differential reading or differential result and input 1
  • Simultaneous display of both inputs
  • Resolution of 0.1* to 1000* autoranging
  • Switchable thermocouple types K / T / J / R / N / E / S
  • Infra-Red compatability
  • Full retention of thermocouple type and temperature scale
  • User configurable Auto Swith Off capability
  • Overrange / Open circuit sensor indication
  • Low battery indication
  • Supplied complete with shock resistant holster
