More about the PrimeTest 100

One of the most popular PAT testers in the UK, the PrimeTest 100 has built-in test sequences and smart technology to help you test a wide range of equipment quickly and easily.

Simply push one button to run through the pre-programmed test sequences for Class 1 equipment, Class 2 equipment or Leads. Connect the PrimeTest 100 to a power outlet and it will also check the socket wiring and mains voltage.

Its large digital display shows test result values, as well as a PASS or FAIL indication. The PrimeTest 100 is portable and battery powered, to help you work faster and more efficiently, with no need for a mains connection.

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 100 to enable the input and storage of test records alongside barcode scanning, label printing, photo tagging and reporting.

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