  • The 719Pro includes a full functioning loop calibrator that sources, simulates and measures mA signals and more making it the ideal test tool for calibrating high accuracy transmitters, pressure switches and pressure gauges.

    Get the ultimate in measurement flexibility with the large backlit screen, which displays three parameters at once:

    • Pressure measurement from internal or external sensor
    • Sourced/simulated or measured mA values
    • Temperature measured by optional RTD probe


Số lượng
  • Unique integrated electric pump for one handed pressure calibration
  • Test pressure switches easily with easy-to-use switch test function
  • Precision pressure adjust vernier for easy and accurate pressure calibration
  • Ideal accuracy and performance (0.025 %) for reference class transmitter calibration
  • 30 PSI, 150 PSI and 300 PSI pressure ranges
  • Programmable pressure calibrator pump limit:
    • Eliminates over-pressurization
    • Allows the user to program target pressures for pumping
  • Extended pressure measurement range with any of 29 700Pxx Pressure Modules
  • Pump cleanout ports reduce pump failures from moisture and fluid damage
  • Fluid trap included with the unit to mitigate chance of fluid damage in at-risk applications
  • Precision temperature measurement with optional RTD probe
