Seaward Primetest 250+ PAT Tester -

Seaward Primetest 250+ Downloadable PAT Tester

PAT testing made simple for a cost that won't break the bank - this is Seaward's PrimeTest 250 Plus PAT tester, a handheld, easy-to-use, cost-effective PAT tester with integrated downloadable memory storage, making it significantly easier to manage your PAT testing records.

Comprehensive Range of Electrical Tests

Capable of performing all testing procedures as required by the IET Code of Practice, this PAT tester gives quick, easy access to all testing functions via dedicated testing buttons on the front of the tester. 

The PrimeTest 250 Plus can test it all - use it to test:

  • Low current earth continuity
  • Insulation resistance at 250/500V
  • IEC leads
  • Protective conductor current
  • Touch current tests
  • 3 phase leakage current (requires 3 phase adaptor)
  • Alternative leakage
  • RCD (30mA and 150mA) and power socket tests
  • Long Lead
  • Test for Class 1 equipment with no exposed parts and a Class 2 FE test sequence to coincide with the new equipment class included in the 5th edition.

You can use the PT250+ to test both class I and class II appliances (including IT equipment), IEC leads and extension leads and - via the use of adaptors (sold separately) - this tester is also suitable for testing 110V and 415V (3 phase) equipment.

Manage Your Testing Records with Fully Downloadable Memory Storage

The PrimeTest 250 Plus can store up to 999 individual appliance testing records in its internal memory. When you've tested something, simply press the single save key and the record will be stored, time/date stamped ready for further use.

When you're done testing for the day, connect your PrimeTest 250+ up to your PC using a USB cable and download the records directly onto your computer.

The PrimeTest 250+ is one of the few downloadable PAT testers which includes its download utility as standard - records are downloaded into standard CSV format, compatible with leading spreadsheet programs such as Microsoft Excel.

For those who require professional reports and certificates, you can also opt to purchase Seaward's PATGuard Elite 3 software which gives you a comprehensive database of PAT records, allows you to schedule inspections and tests and create reports etc.

Seamless Plug & Print with the Optional Test n Tag Pro Serial Printer

Use the PrimeTest 250 Plus with the Test n Tag Pro Serial Printer (sold separately and available in kit versions of the PT250+) to create professional, low cost inspection and testing labels as you're testing.

The Test n Tag Pro is designed to seamlessly work with the PT250+'s memory storage capabilities; just connect up the printer when testing and hit the print button when you're ready to print out your label.

Every label roll for the Test n Tag Pro has over 400 labels, ensuring you can test a large amount of appliances before replacing at a later date.

Expand your Reporting Capabilities with Seaward PATGuard 3 Software

Note: PATGuard 3 is an optional purchase and is not required to use the PT250+'s download capabilities.

Although the PT250+ includes a download utility so you can download for free into a CSV file compatible with Microsoft Excel, you can vastly increase the capabilities of your PT250+ by adding Seaward's PATGuard Elite 3 software to your purchase.

Available in some of the PT250+ or for purchase separately, PATGuard 3 is a yearly-licensed software package* which gives you a number of benefits, including:

  • Professional user interface gives you quick, seamless access to your PAT records
  • Tag photos to sites, locations, asset IDs and testing results
  • Compatible with a wide variety of Seaward PAT testers, including the PT250+ and Apollo series
  • Electrical risk assessment tool quickly determines risk-based retest periods for electrical appliances
  • Universal risk assessment tool for any workplace hazards
  • Create an extensive range of editable detailed and summary reports
  • Create test and inspection reports for fire detection/fire alarm systems and emergency lighting
  • Auto-scheduler function notifies the user when assets are ready for retesting
  • Generate professional invoices
  • Create customisable exports of testing records in CSV format

*Note: we also stock a license-free version of PATGuard 3 which has no yearly recurring fee.
