Seaward PrimeTest 100 PAT Tester Details

The Seaward PrimeTest 100 PAT tester is the upgraded version of the entry-level Seaward PrimeTest 50.

This PAT tester is a portable, easy-to-use and fast instrument ideal for those with a low volume of appliances to test. We highly recommend this tester if you want to PAT test in a charity shop, in a small office or other similar application. With the PrimeTest 100, you'll have everything you need for testing all basic electrical appliances including IT equipment such as computers and monitors, both class I and class II appliances, IEC and power leads and - via the use of optional 110V adaptors - the PT100 can also be used to test 110V equipment.

The main difference between the PrimeTest 100 and the PrimeTest 50 is that the PT100 includes the ability to show full testing results, allowing you to keep more comprehensive records. The PT50 only shows whether an appliance passes or fails the test; the PT100 will instead tell if you the appliance has passed or failed the test and show you the full testing results.

Using the PrimeTest 100 is simple, even for a beginner.  The tester has just three buttons: a class I appliance, class II appliance and cord button. Pressing each after connecting to the appliance and/or lead will automatically cycle through applicable tests such as earth continuity, insulation, leakage or wiring, then show you all the results so you can jot them down.

You can even connect the PrimeTest 100 directly to a power outlet and it'll automatically check the socket's wiring and mains voltage!

Seaward PATMobile App Compatible - Power Up Your PAT Tester

Seaward's PrimeTest 100 is a manual PAT tester - it does not have built-in memory to record your testing results. Instead, you'll need to use a PAT testing logbook to keep a record of all your testing results, or you can use Seaward's PATMobile app to log results, tag photos, export data and print labels*!

Available as a free download for both Android and iOS, PATMobile gives you abilities usually only found on more expensive PAT testers. Using this app, you'll find it significantly easier to keep records of all your testing.

The following video from Seaward shows how the PATMobile app works alongside the PrimeTest series.

*Optional printer required for label printing. Only works with Android.

Seaward PrimeTest 100 PAT Tester Key Features

  • Compact, lightweight design - move from appliance to appliance quickly, easily and without having to move things around
  • Simple operation - even for PAT testing beginners, the PrimeTest 100 is ideal. Simply press one of the three buttons on the front of the tester, connect up an appliance and the tester will do the rest
  • Suitable for different testing types - the PrimeTest 100 includes the ability to carry out earth continuity, insulation, leakage and wiring testing on Class I and Class II appliances as well as cords
  • Full testing result display - once a test is completed this PAT tester will show the result as a full numerical reading as well as displaying a pass/fail value for reference
  • Battery powered - don't worry about needing a mains outlet; the PrimeTest 100 can be taken wherever you need it
