The Seaward Powertest 1557 is ideally suited to domestic engineers and carries out the standard tests required by the 17th Edition wiring regulations. It's an easy-to-use tester and comes supplied with a hard carry case and basic calibration checker.

Thanks to a clever bit of design, the Seaward Powertest 1557 includes a cordless probe for use with the tester, allowing the user to hold the tester in one hand and see the results at the same time. This is ideal when performing continuity testing.

Weighing in at a mere 900 grams, the Seaward Powertest 1557 is lightweight and it can do any test that you require at the turn of a knob, including:

  • Earth Continuity, Insulation (100v, 250v, 500v)
