Megger's new S1-568 5 kV insulation resistance tester has been specially developed for the toughest of Power Industry testing environments and for the largest of test samples / longest of cables. These top end instruments are targeted at power utilities and service companies working in generation, transmission and distribution markets where extra heavy duty is called for! The S1-568's class-leading charge current (6 mA!), noise rejection (8 mA rejection!), and four software filters (10, 30, 100, and 200 seconds) make the S1-Series Megger's most advanced DC insulation resistance testers to date. Naturally, it is Cat 4 600V, has remote operation via USB, USB or Bluetooth download, comes with the acclaimed Megger PowerDB Lite asset managment software, has rapid-charge Li-ion batteries with 6 hour operation off a charge, and does all the tests you would expect for the biggest of cables, motors, generators, circuit breakers, and bushings. In all, the ultimate 5 kV tester!!
