Imagine the DEWE-560-PNA running for 2-3 hours from its own internal batteries - wouldn't that be amazing? Well, that's exactly what we've done with the 570 model. Suddenly the DEWE-570-PNA goes to the head of the pack among portable power testers. With 4 x voltage and 4 x current inputs, and packaged in a rugged high-impact enclosure, we have pushed the envelope tremendously in putting a powerful analyzer into an incredibly convenient and portable box!

Isolation? Of course. The DEWE-570-PNA meets and exceeds all of the international norms and specifications that you need and expect. In one incredible package we have put a powerful 3-phase analyzer capable of handling any base frequency - including variable base frequencies - up to 800 Hz!
