PowerMaster 3 Series

Introducing the Revolutionary PowerMaster 3 Series Hand-held 3-Phase Meter Site Tester

The PowerMaster 3 Series is an ultra-compact field instrument with a true 3-phase analyzing reference standard that performs various metering site accuracy tests.

Customer load Meter Testing, CT/PT ratio testing, CT/PT burden measurement, meter register/demand testing and wiring verification are all easily performed with this extremely portable, hand-held analyzer.

In addition, with the new Model 335, phantom load meter testing and CT burden added testing are available to complete your field testing needs.  With many advanced features, this new pint-sized analyzer is revolutionizing field testing as we know it.
