Seaward Powertest 1557 Multifunction Installation Tester Details

Multifunction

Made for electrical contractors, electrical engineers and ideal for use in training institutions, the Seaward Powertest 1557 is an entry-level, low-cost multifunction electrical installation tester.

Designed and manufactured in Britain by Seaward. This tester will perform all basic electrical checks, including earth continuity, insulation (with voltages of 100V, 250V and 500V), non-trip loop impedance, line impedance, RCD trip current and basic voltage/frequency measurements.

Testing with the Powertest 1557 is simple - just turn the rotary dial on the front to the test you want, then activate using the test button on the front of the tester. As standard the 1557 also includes Seaward's uniquely-designed cordless probe - with this, you'll be able to activate testing procedures using the probe itself, freeing up your hands to work more efficiently.

The Powertest 1557 is one of the smallest and lightest multifunction testers on the market. It's actually small and light enough to be easily held in one hand!

Good tester for someone starting out on domestic electrics . I got this as a spare for my megger 1730. It's a good tester but budget for better leads as the ones supplied are not very good
