PowerSite meters provide extensive capabilities as demand analyzers, harmonic analyzers, power quality analyzers, power meters, and data loggers. PowerSite analyzers are the smallest, most cost effective instruments for the measurement and analysis of three phase electric power. Monitor, log, and analyze voltage, current, and power. Use it for three-phase, two-phase, single-phase, 2-1/2 phase, 2CT/2PT, DC, 50Hz, 60Hz, and 400Hz systems anywhere in the world. Comes in 7 languages!

The PS3000 Energy Analyzer is the workhorse of the family. It performs all measurements required for demand analysis on all types of systems in the world. It has been used under all conditions (one is in even in use at The South Pole). It has great harmonic analysis abilities, good swell and sag abilities, and some transient capabilities. Its small size and ease of use have made it a winner for years!

The PS4000 Power Quality Analyzer is our most powerful analyzer. It is a stunning technical achievement, oriented towards the demanding needs of power quality analysis. In addition to doing all that the PS3000 does, it does complete harmonic analysis on every cycle, captures swells and sags on every half cycle, and captures transients with a resolution of 10 microseconds. It does all this in a package that is hand-sized and weighs less than 2 pounds!

The PS250 Power Monitor is a more cost-effective version of the PS3000. It retains the core capabilities required for energy audits and demand analysis and incorporates a new "verify connections" feature that clears up connection problems before logging begins and without the need for a laptop computer. This makes it easy to set it up and leave for hours, days, or even months at a time without worrying about your data. It is the premier compact power data logger.
