Simply powerful intrinsically safe calibration tool!

The new ecom 725Ex Intrinsically Safe Multifunction Process Calibrator is powerful yet easy-to-use. Combined with the new ecom 700PEx Pressure Modules, the 725Ex is able to calibrate almost any process instrument likely to need service in an area where explosive gasses may be present.



  • Measure volts dc, mA, RTDs, thermocouples, frequency and ohms
  • Source or simulate volts dc, mA, RTDs, thermocouples,frequency and ohms
  • Two channel simultaneous source and measure capability for calibration of transmitters
  • Power transmitters with internal loop supply
  • Store frequently-used test setups for later use
  • Pressure measurement to 3,000 psi/200 bar using any of the 8 intrinsically safe 700PEx Pressure Modules
  • Pressure switch test function to capture set, reset and deadband values
