This is the Megger PAT420, a professional-grade PAT tester that's also the upgraded version of the Megger PAT410. New features exclusive to this model include a wider range of earth bond/continuity test currents (200mA, 10A and 20A) to test a wider amount of appliances at full strength (or use the low current 200mA test for IT equipment) and this tester also comes as standard with its own 110V appliance connector, meaning there are absolutely no external adapters required to test your 110V appliances! The 110V connector makes the Megger PAT420 an excellent choice for those working on construction sites or other areas where 110V tools are regularly used*.
*Note: the PAT420 is also suitable for testing 415V equipment and leads; however you will need to use a set of compatible 415V adapters to do so. You can get a set of adapters from us by following this link.
Megger's PAT tester is designed to help you create a comprehensive record of your testing results, customers and appliance IDs. With built-in 10,000 record memory storage, a full QWERTY keyboard for making text entries and full support for optional barcode scanners and printers for easier asset management/label printing, the PAT420 provides everything you need for cataloguing your PAT testing results.
Downloading from the PAT Tester is simple; just plug in a USB stick, download onto it, and plug it into your PC. Results can be exported in CSV format (compatible with programs such as Microsoft Excel) or alternatively, you can invest in optional third party software Simply Pats to create a full database of your results and gain the ability to create reports and certificates based on your PAT testing data.
The PAT420 is designed to do absolutely all basic PAT tests in accordance with the IT code of practice, as well as more specialist testing modes. It can test both 230 and 110V appliances and includes testing modes such as earth bond/continuity at 200mA, 10A and 25A, insulation testing at 250V and 500V and performs substitute, differential and touch current leakage tests. This tester can also be used for testing extension leads and will check earth bond, insulation, polarity and portable RCDs.
With the PAT420, you can take full control over PAT testing. You can either use the built-in automatic testing routines to speed up your testing, or take full manual control of your tests and adjust the testing times, or the pass limits of appliances.
If you're looking for a professional-grade PAT tester that'll help you test all appliances faster, and let you log all information ready for analysis on a PC, look no further than Megger's PAT420.
