194Y MFM Meter with Ethenet Port

194Y MFM Meter is a three phase electrical network power quality detection device, it provides energy consumption and generation, THD (Total Harmonic Distortion), and Harmonic individual data reading. This 3 phase power monitor is the ideal choice for monitoring and controlling power distribution systems.

Its four direct access keys and LCD displays help you use all the parameters in 3P3W or 3P4W LV installation. 194Y Multifunction Power Meter has a built-in 4 tariffs energy logger function with onboard memory that can record the last three-month energy data free. You can set max 12-segment record period that can be used as a commercial billing unit.
