The PowerTest 1557 multifunction installation tester
The PowerTest 1557 is a multi function installation tester with integral probe, allowing the instrument to be held and the results to be read at the same time.
The PowerTest 1557 is also very fast, performing earth loop, line loop, PFC and PSC tests with one press of a button in under 5 seconds. It's lightweight, handheld and battery powered.
Thanks to a clever bit of design, Seaward have included a cordless probe for use with the tester, meaning you can hold the tester and see the results at the same time. Weighing in at a mere 900 grams, it’s light too. And it can do any test that you require at the turn of a knob, including Earth Continuity, Insulation (100v, 250v, 500v), Non-trip Loop Impedance, Line Impedance, RCD trip line, RCD trip current and voltage / frequency measurements.
This instrument comes complete with the manufacturers dated calibration certificate. Please be aware that these certificates are generic and may also be time lapsed. If you would prefer a personalised full traceable calibration certificate applied to the equipment before dispatch, then please select this option from the drop-down menu above, an additional calibration charge will apply.
Limited Edition package includes:
- PowerTest 1557 multifunction tester
- Rugged carry case
- Test lead set
- Shrouded safety plugs
- Shrouded safety test probes
- Cordless shrouded safety test probe
