• Test items:During working status, test the temperature, voltage, current, power and so on.
    • The test instruments they used before can not meet the requirement in precision.
  • Test requirements:
    • High precision, temperature measurement error should be less than 0.7 degrees.
    • Remote control is needed.
    • PC software can record power and temperature data generate report.
    • Record the electrical parameters and temperature synchronously.


  1. Ethernet interface (standard) can realize the remote control and data record function.
  2. Easy to use.
  3. High precision recorder.

Customer Feedback

  • Easy to use.
  • Meet all the test requirements.
  • Remote monitoring and data recording.
  • Record the electrical parameters and temperature synchronously. It’s convenient to analyze the data.
e.g. GateWT
Customers use application software like GA10, and GateWT
The WT310E/WT330E series has a Command compatibility mode with previous WT210/WT230 series. Under that special operating mode, the WT310E/WT330E series works like the WT310/WT330 series.

Power Analyzers

Power Analyzers

A power analyzer measures electrical power characteristics of devices that generate, transform, or consume electricity. Also called power meters or wattmeters, these devices measure parameters such as true power (watts), power factor, harmonics and efficiency in inverters, motor drives, lighting, home appliances, office equipment, power supplies, industrial machinery and other devices. Power analyzers also enable engineers to minimize energy loss due to distorted, transient waveforms in power electronics such as inverters, motors, lighting circuits, and power supplies. 

Yokogawa, the world's leading manufacturer of electrical power analyzers, provides a broad selection to satisfy all requirements.
