The Martindale Professional Kit HPAT550 enhances everything you loved about the Essentials version by incorporating powerful software to improve your PAT testing workflow. It maintains the intuitive one-button auto-test feature, a clear colour display with instant PASS/FAIL indicators, selectable 250 V/500 V insulation testing, and a safe 200 mA earth bond test—all packed into a lightweight, USB-C rechargeable handheld unit.
What distinguishes the Professional Kit is the inclusion of Simply Pats Manual Entry Software, which allows for seamless logging and reporting of test results. The kit also comes with all the essentials: IEC lead adapters, a microwave leakage detector, a UK socket tester, over 1,000 labels for tagging and record-keeping, a durable carry case, an insulated screwdriver set, and access to online PAT training. In one compact, professional-grade package, you receive testing hardware, software, accessories, and training—all designed for efficient, accurate, and regulation-compliant PAT inspections across offices, schools, data centres, and industrial sites.
