The Megger PAT320 PAT Tester has 110V and 230V sockets which allow it to be used on units from domestic appliances to industrial power tools without the need for an adaptor. It can perform a 200mA IT safe earth bond test, insulation testing at 250V/500V, substitute leakage test, differential leakage test, touch current measurement, portable RCD testing, extension lead testing, fuse testing and load and run testing.

The Megger PAT320 has individual test buttons that allow it to perform specific tests without a full sequence. There are also automatic test sequences for Class I and Class II appliances and extension leads. The user can navigate the internal menus that are shown on the colour, digital screen and the tester provides both numeric readouts and a PASS/FAIL indication for each test.

The sturdy design of the Megger PAT320 means it is suitable for use in domestic, commercial and industrial environments. It comes supplied with an earth bond test lead, an extension lead adaptor, calibration certificate and a carry case. The tester is covered by a twelve-month warranty.
