PrimeTest 50 Portable Appliance Tester

The PrimeTest 50 is one of the most reliable and easy-to-use PAT testers available, designed for users who require a simple, portable, and cost-effective solution for electrical safety checks.

With three dedicated test buttons, the PrimeTest 50 makes it effortless to select the appropriate test. A smart internal circuit identifies whether an appliance or extension lead is connected, while the large LCD screen displays clear PASS/FAIL indications for confidence in every result.

Capable of testing Class I, Class II, IT equipment, and extension leads, the PrimeTest 50 is ideal for organisations performing smaller quantities of testing or conducting enhanced visual inspections.

Seaward’s unique ZAP technology ensures earth continuity readings remain accurate even through rust, limescale, or other contamination, where other testers struggle.

The PrimeTest 50 is also compatible with the PATMobile App, allowing users to digitise their workflow with barcode scanning, wireless label printing, photo tagging, and reporting — a perfect bridge between manual and digital PAT testing.
