The Seaward Apollo 500+ PAT Tester is a high-spec PAT tester that combines sophisticated testing features with a large internal memory and intuitive operation. It can test appliances with a 200mA earth bond test, 250V/500V insulation tests, load and run test, touch/alternative leakage current measurement, and polarity checking. These capabilities make the tester suitable for the comprehensive testing of Class I and Class II appliances as well as extension leads. There are also RCD and power socket testing functions.

One of the main features of the Seaward Apollo 500+ is its risk-based assessment tool which calculates an appropriate retest date based on official criteria. Operating the tester is extremely easy thanks to the improved interface and database search function. The instrument has a full QWERTY keyboard — ideal for appliance data entry — as well as clear navigation buttons which help select the test function using the menus on the clear colour display.

A large internal memory has enough space for up to 10,000 test results which makes the Seaward Apollo 500+ ideal for high-volume testing. It is possible to download results wirelessly via Bluetooth or via the USB port and it is compatible with optional Seaward PATGuard 3 software which is a great tool for analysis and reporting.

The Seaward Apollo 500+ can work with an optional Seaward Test n Tag Elite 2 Printer to produce customised PAT labels with a company logo, test result, appliance ID and even a 2D QR code. This allows the end user to scan the label and access all the test information using their smartphone. A Seaward QR and Barcode Scanner can also be purchased separately to enable the tester to instantly read appliance information from previous labels and QR codes.
