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

Calibrators are used to validate the accuracy of field instrumentation, which are subject to harsh environmental conditions and wear and tear. Over time, their integrity degrades, which, depending on the severity, could lead to plant shutdowns and thus opportunity costs, or personnel injury. Calibrators achieve this by being able to source, as well as measure, precision signals. Yokogawa offers an extensive portfolio of handheld calibratrion equipment, ranging from process multimeters, pressure calibrators, to multi-function units. No matter the situation, you can count on Yokogawa's calibrators for their:


  • Calibrate anything from data loggers, temperature controllers, thermometers, multimeters, and pressure transmitters
  • Source and measure voltage, current, resistance, temperature, pressure, pulse and frequency
  • Ergonomic interfaces engineered to work with Yokogawa as well as third party products
  • A host of functions for verifying equipment response including output ramping, output stepping, and loop power (simultaneously stimulate a device and measure its response)

Minimal Training

  • Quikcly and efficient get your plant personnel and contracters up to speed so they can focus more time on their tasks 
  • Intuitive controls allow users to quickly store setup files, save data to internal memory, and alternate between sourcing and measuring 


  • Rugged design ensures units can withstand harsh environments  
  • Calibrators conform to IP54, EN61010-1 CATIV600V and CATIII1000V safety design, EMC EN 61326 Class B, EN 55011 Class B Group1 EN 61000-3-2; EN 61000-3-3, EN61326


  • 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 PM100 External Pressure Sensor which enables pressure calibration in even higher pressure ranges using the CA700

  • 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.
