More about the PrimeTest 250+

Enabling simple, professional and fast PAT testing, this versatile tester features all of the required tests of the IET 5th Edition Code of Practice and BS EN50699, along with USB download. It is also fully compatible with the Test n Tag Pro serial printer for quick and easy label printing without any setup required – just plug and print.

Using Seaward’s free datalogger program and pressing a single download key allows test result data to be quickly and easily transferred from the PrimeTest 250+ to PC at the press of a button. Data is downloaded in a simple CSV spreadsheet format for your PAT records or alternatively the CSV data can be imported directly into Seaward’s PATGuard 3 software for more enhanced record keeping, reporting and certification.

Seaward’s unique ‘ZAP’ technology ensures that earth continuity measurements are accurate in situations where other testers struggle to provide reliable measurements, such as measuring through rust, limescale and other surface contamination.

The PrimeTest Series Testers can be used with our free PATMobile App as part of a combined record keeping and reporting solution. The PATMobile App works with the PrimeTest 250+ to enable the input and storage of test records alongside barcode scanning, wireless label printing, photo tagging and mobile reporting.

Built in Britain and used by 1,000’s of organisations every day.
