Maintain optimal equipment performance with Yokogawa’s high accuracy calibrators.

Yokogawa’s growing line of calibration equipment includes multifunction and process calibrators capable of measuring voltage, current, resistance, thermocouple, RTD, frequency, and pulse signals.

Calibrators are used to check and maintain the accuracy of measuring instruments and process control devices. Calibration of process instruments is necessary for checking instrument performance and ensuring that a particular instrument meets its specifications from both the laboratory and production line.

Yokogawa calibrators support a variety of applications and can provide calibration of measurement instruments including pressure and temperature transmitters, analog meters, and data loggers. Our calibration devices feature ergonomic interfaces for improved functionality and are engineered to work both with Yokogawa and competitor products, allowing customers to maintain high performance from their equipment while keeping the specifications of the calibration process.

  • The CA300 Series is a high accuracy source and measure portable handheld calibrator used to inspect and maintain the accuracy of control devices such as temperature controllers, temperature transmitters, temperature sensors and other process devices which are used in process plants, industry machinery, and manufacturing. Available in 3 models, the CA310, CA320, and CA330 provide an ergonomic and friendly user-interface making it easy to use.

  • The CA700 is a highly accurate and highly functional pressure calibrator specifically designed for the calibration of differential pressure and pressure transmitters, which are widely used in plant processes these days and are improving in terms of accuracy and functionality.

  • The CA150 Handy Calibrator is a comprehensive source and measure instrument for your calibration and equipment checking needs at maintenance sites. The CA150 can simultaneously source and measure voltage, current, resistance, Thermocouple, RTD, and Pulse signals.

  • The CA71 Portable Calibrator is a small, lightweight, multifunction calibrator that can simultaneously source and measure voltage, current, resistance, TC, RTD, frequency, and pulse signals. The Handy Calibrator incorporates rotary switches for simple handling. Just open the carrying case cover and connect the cables, and you're ready to take measurements.

  • The Yokogawa CA450 Process Multimeter is a portable test instrument to combine a digital RMS multimeter and a loop calibrator to give process technicians the same functionality in one tool.


After a disastrous 2009, the large publicly held test companies enjoyed booming business in 2010.
