PITE 3531 Power Quality Analyzer

PITE 3531 Power Quality Analyzer

PITE 3531 is 3p/3w and 3p/4w testing and analyzing device for the quality of power grid. It provides multiple analyzing for electric harmonic, voltage/current/frequency, 3-phase unbalance, power and energy, data recording and so on...

Why PITE?
An Easy-to-use power quality tool is a "must-have" for any person who maintains or troubleshoots three phase power. PITE three-phase power quality meters help you locate, predict, prevent and troubleshoot problems in power distribution systems. We offer a full range of trouble-shooters for the prevention and analyzing of the power quality problem. It is not only your problem solver, but also a money saver.
