Make your life easier! Use a hand-held, battery-powered Seaward PrimeTest 100 (230V) A PAT Tester to perform quality tests for an affordable price.

Includes New Calibration Certificate worth over £70!

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

The Primetest 100 is compliant with the 5th Edition Code of Practice and has been updated in October 2020 to ensure this, these changes include;

  • 250V insulation Resistance Test and new settings menu where you can choose the default test voltage (you can switch to the non-default test voltage (250V /500v) by holding down the test key)
  • Select pass-fail values for earth continuity (0.1, 0.2, 0.3Ω) from the menu
  • Long lead testing
  • Class 1 equipment with no exposed parts and a Class 2 FE test sequence
  • Pass-fail limit of 5mA for Equivalent Leakage test

The Primetest 100 keeps its previous reputation as a feature-packed manual PAT tester. It is hand-held and battery-powered, giving you great freedom when PAT testing. This PAT tester is easy-to-use and has three operational modes. Simply pushing a button will give you the option of PAT Test mode, Class I and II, IEC Lead Test mode or simply plug into a power socket to automatically test it.

The Seaward PrimeTest 100 PAT Tester has a bright display which shows actual test readings. Therefore you can use the readings to test extension cables and appliances with long leads. This allows you to decide whether the item is a pass or fail.

You can also test 110v appliances with the Seaward PrimeTest 100; you just need to purchase two extra leads, see PASSPTA2 (IEC socket to 110v plug 16amp) and PASSPTA9 (240v UK 13amp plug to 110v socket 16amp).

Inside this bundle, you'll receive all of the following items which are included as standard by the manufacturer:

  • Seaward PrimeTest 100 PAT Tester - New 5th Edition Update
  • 0.5m Extension Adaptor
  • 6 x AA Batteries
  • Earth Bond Lead 1m
  • Carrying Case
  • FREE Certificate of Calibration -  worth over £70, we'll calibrate your new PAT tester in our calibration laboratory and give you a full, accredited calibration certificate in your name from the date of purchase*

* Please note that because the item comes with calibration from date of purchase, our team will need to insert the new batteries into the unit in order to test it. Therefore the supplied batteries will already be installed in the tester when it arrives. 

Lightweight, Portable And Simple-To-Use

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 (Optional printer required for label printing. Only works with Android.)

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.

Available for both Android and iOS tablets and smartphones, PATMobile allows you to perform various tasks, including:

  • Log Your PAT Testing Results - create a manual, digital log of your PAT testing records. All results can be recalled and exported into Excel files for reporting purposes
  • Tag Photos - use your smartphone or tablet's camera to take a photo of the appliance you're testing and tag it seamlessly against an appliance ID number
  • Scan Barcode Labels - easily enter appliance ID numbers into the app by scanning a barcoded label (sold separately)
  • Print Labels - connect to an optional Seaward printer (sold separately) to create your own PAT labels (please note that this only works for Android smartphones/tablets and is not compatible with iOS)

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
