PAT Tester Comparison
What's the best entry-level PAT tester?
Introduction
All three of these testers are entry-level portable appliance testers (PAT) that to give users access to the bare minimum to ensure compliance with the rules and regulations set down by the IET Code of Practice. Designed to be easy to use, entry-level PAT testers are ideal for beginner users or low-volume applications without many appliances and don't have the complex advanced features found on mid-range and professional-grade PAT testing machines.
The main difference between entry-level PAT testers and their upgraded counterparts is that these testers only show a PASS/FAIL indicator when testing, whereas more advanced testers will show PASS/FAIL alongside a full test reading for records. The simple indication means you can see at a glance whether the connected appliance or cord has passed the test, but also means you won't get a full reading and can't jot it down as a reference. For beginner users, a PASS/FAIL indicator is more than suitable for ensuring full compliance with PAT regulations and these testers are found in shops, schools, offices and much more across the world.
But which of these testers is right for you? All three of them are excellent at what they do (and you certainly won't be disapointed with any of them!) but they still vary in abilities and it is important to understand the differences when considering a purchase. That's exactly what this guide is for; hopefully by following it you can decide on your perfect PAT tester and get testing your appliances!
