Description

The Megger PAT420 PAT Tester has an integrated 110V socket meaning that it can perform appliance tests on both 230V and 110V appliances without the need for an adaptor. This makes it suitable for use in commercial and industrial settings.

The PAT tester can perform a range of tests and measurements including earth bond continuity, insulation resistance, substitute/differential/leakage current, portable RCD checking, fuse test and load & run testing. It is also possible to test extension leads with the Megger PAT420 using the supplied adaptor and there is an option for high current earth bond testing at 10A and 25A.

The Megger PAT420 has a very large internal memory for 10,000 records and this storage capacity is fully downloadable via the USB port. The user can add extra detail, for example appliance information and test dates, using the full QWERTY keyboard whilst individual buttons immediately trigger the most frequently-used tests.

The large memory and integrated 110V socket make the Megger PAT420 ideal for high-volume testing where a wide range of appliances will be tested. The tester comes with an earth bond test lead, extension lead adaptor, cloverleaf adaptor and carry case.
