T/C Simulator (DigiSim 38517)

The T/C Simulator (DigiSim 38517) is a micro-controller based portable, battery-operated, precision instrument designed for sourcing and measuring mV & T/C signals. A graphical (128x64) LCD with backlight gives excellent user interface. It is designed to calibrate instruments taking either T/Cs or mV as an input and retain its precision & repeatability over long periods in worst environmental conditions. An exceptionally stable voltage source provides continuously variable precision output signals with two ten-turn potentiometers.


  • Simulates & measures Ohms & RTDs
  • High precision, accuracy, reliability & longevity
  • Graphical(128x64) LCD with backlight for excellent UI
  • Simultaneous display of temperature & mV
  • Auto or Manual cold junction compensation (CJC)
  • Continuous indication of cold junction temperature
  • Compact in size and built for toughest environments
  • Unique self-check facility ensures reliable operations
  • Powered by AC/DC adapter or 9V Ni-Mh battery


  • Simulates & measures T/Cs with Auto/Manual CJC
  • Calibrates temperature indicators with T/C input
  • Works as voltage(mV) source
  • Calibrates temperature controllers and transmitters
