Megger's top-of-the-range PAT tester, the PAT450 performs absolutely every test a PAT technician will need.

The upgrade to the PAT420 and PAT410, the PAT450 is an advanced PAT tester with fully downloadable, 10,000 record memory. It's suitable for use on both 230V and 110V appliances, can test extension leads, IT equipment and can even test appliances found in workshops thanks to its unique flash testing function at 1.5kV and 3kV.

With the PAT450's built-in full colour screen, it's quick and easy to view and amend testing data. A full QWERTY keyboard is included for data entry and a port for an optional barcode scanner and printer means you can speed up asset recall and print data out in the field.

The PAT450 has two modes: automatic and manual. The automatic sequences will automatically cycle through applicable tests for an attached appliance, while the manual testing mode gives the user full control over testing times and PASS/FAIL limits.
