This PAT Tester can perform the following tests:

  • Low current earth continuity test
  • Point-to-point testing (earth continuity and insulation resistance)*
  • Insulation resistance test
  • IEC lead test
  • Protective conductor current test
  • Touch current test
  • Load power/current test
  • Alternative leakage current test
  • RCD test
  • Power socket test

*For point-to-point testing, optional Accessory is required.


What’s New?

Hardware Update

The hardware features of the Apollo haven’t deviated too much from the original hardware, but now feature an interchangeable rechargeable battery, meaning reduced downtime if you have a large number of appliances to test.

The tester will now be supplied with an additional wiring harness and removable battery

Firmware Update

The biggest change to the Apollo 400 is the new firmware update and the improved usability of the user interface, meaning the update has been specifically targeted to user’s needs.

The Apollo 400+ updated features:

  • New user permissions for Bluetooth
  • Delete unwanted results
  • Improved data view – Allows the user to sort data and can filter by a number of methods including PASS/Fail status
  • A more advanced search function
  • Automatically print test results option added to the ‘After test’ option
  • ‘Worst’ or ‘Last’ has been added as an option to the leakage test
  • Delete items from the predictive drop-down lists
  • USB on-the-go technology means you can download directly to an Android device
  • Name downloaded files with unique identifiers to find them easier
  • Addition of a socket outlet test which measures main voltage and outlet wiring polarity
  • The asset ID is now displayed on all test screens allowing you to keep track of what you are currently testing
  • Review step – Check test details before making final comments

The accessories that come supplied with the tester have also been improved; the test leads now feature a stronger PVC insulation and sturdier probes for more demanding usage.


The Apollo 400+ is compatible with the new PAT guard 3.4 which now includes Time Manager (Software sold separately)
