Power Master® 3 Series

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 3-phase power 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 3-phase power analyzer is revolutionizing field testing as we know it.
