Seaward PrimeTest 250 PAT Tester Details

The PrimeTest 250 builds upon the functionality of other PAT testers in the PrimeTest series and includes several additional testing procedures so even more equipment can be checked for safety!

Like all models in the PrimeTest series, the PT250 has been designed with ease of use in mind. Simply connect your appliance (using the help diagrams on the front of the tester for reference), press the button you need and the tester will automatically carry out the test for you. Once done, the screen will display whether an appliance has PASSED/FAILED a test and also show you the full results for reference.

Want to see how it works? This product demo from Seaward outlines some of the functions of the PrimeTest 250.

The PT250 is made in compliance with the latest regulations in the IET Code of Practice. It can test earth continuity, insulation resistance, equivalent leakage, IEC leads, protective conductor current, touch current and even includes special functions for testing RCD trip time, power sockets and 3 phase differential leakage current*.

*3 phase adaptor (sold separately) required for 3 phase testing.
