T/C Simulator HandySim 38527

The Digital T/C Simulator (DigiSim 38527) is a portable, battery-operated, precision 4 digit simulator for mV & T/C input instruments. It is designed to source mV signals as well as simulate upto three specified T/Cs in international standards. In addition to simulation, it can also be used as a precision mV and Temperature Indicator. A self-check facility is provided to establish correct functioning of all the circuit blocks.


  • Sources and measures precise mV and upto 3 T/Cs
  • Useful for calibration of temperature indicators
  • Range : 80mV and T/Cs as per tech specs
  • Resolution : 1°C for T/Cs and 20 μV
  • Accuracy : ±0.05% of rdg 0.05% of F.S.±2 digit
  • Display shows temperature directly in °C or mV
  • Auto and manual CJ compensation for T/C simulation
  • Suitable for mass calibration jobs during shutdowns
  • Uses 9V Ni-Cd battery with longer life for field use
  • Unique Self-Check facility ensures reliability
