Yokogawa CA700 Pressure Calibrator Product Highlights

  • The CA700 is a highly accurate and functional pressure calibrator specifically designed for calibration of differential pressure and gauge pressure transmitters.
  • The CA700 with silicon resonant pressure sensor has achieved the highest accuracy and widest range in the portable class, enabling field calibration with greater accuracy than ever before.
  • Also, has the highest resolution and widest range of any handheld portable in its class.
  • Supports ” As Found”, “As Left” data and error rate (%), hence it stores calibration procedures for pressure transmitters and pressure switched which allow strong support for field calibration and maintenance work.
  • Housed in a robust IP54 dustproof, and waterproof case for use in harsh environments.
  • Available in three model ranges: Low-pressure, Medium-pressure or High-pressure with selectable high-performance hand pumps for each range.


Applications for the CA700 Pressure Calibrator include:

  • Field calibration of differential pressure and pressure transmitters
  • Pressure switch test
  • Check and I/O adjustment of an electro-pneumatic converter
  • 4 – 20 mA SIMULATE (two-wire transmitter simulator)
  • Two-wire transmitter loop test
  • Input command check and adjustment of recorders and controllers
