Power Monitors


    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.

  • CTW Current Transformers

    The CTW Series are clamp-on current transformers that can be installed much easier than conventional current transformers, whereby saving installation cost. These transformers are particularly useful when expanding existing system since you can attach them to a cable without having to cut it. Standard lineup includes 100 A, 200 A, 500 A and 800 A models. Also compact and light-weight 100 A and 300 A models are available. Each of CTW models contains a built-in device for suppressing hazardous voltages that prevents a burnout or outage at the open-circuit of secondary line.


    The Yokogawa CW500 is a portable power meter that utilizes current clamp-on probes, navigation screens and quick start guides. These features enable user-friendly power consumption and power quality measurements in the field that conform to IEC61000-4-30 Class S.

  • PR300 Power and Energy Meter

    PR300 is a panel-mounted meter designed to meet two user needs: a power facility meter and a meter for monitoring energy consumption.
