Portable Power Monitor/Recorder

As the world goes to a more Energy efficient mindset, products are needed to monitor each factory’s energy requirements. The CW500, CW240 and CW120 Power monitor series allows the customer to use a portable recording device to measure voltage, current, watts, VARs, VA, PF, PA, frequency, harmonics, and demand. This 1P2W to 3P4W power monitor provides a visual report of the current power situation to prevent major energy problem and utility over charges.

The CW500 simultaneously monitor the malfunction events of power such as voltage swells, voltage dips or interrupts, by 40kHz sampling and records the occurrence date and time, measured value and 200ms period of waveform of each input.

  • The Yokogawa CW500 is a portable power meter that utilizes current clamp-on probes, navigation screens and quick start guides.


  • The Clamp-on Power Meter CW10 (Single-Phase) is more like a tester type rather than a recorder, which can measure single phase AC and DC Power, Voltage, Currents, Power Factor, Frequency, Harmonics. It will also contribute to workers maintenance of not only consuming equipment but equipment for renewable energy such as solar and wind power generation.


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



    Join us on November 10th where we will start to break down the common causes, effects and solutions to poor power quality, as it relates to low power factor. In this webinar, we will provide several solutions to this common issue and teach you the proven benefits of improved power factor.
