The Martindale HPAT550 Essentials Kit provides a comprehensive and efficient solution for individuals responsible for electrical safety testing. At its core is the HPAT550 Portable Appliance Tester, a user-friendly, handheld device that streamlines PAT testing with a one-button auto-test function and a clear, high-resolution colour display.
Instantly recognisable PASS/FAIL indicators make onsite assessments quick and foolproof, while selectable 250V and 500V insulation tests provide flexibility for surge-protected or sensitive IT equipment. Its IT-safe 200mA earth bond test ensures thorough yet non-disruptive checks, making it ideal for office or data environments.
The HPAT550 is USB-C rechargeable with a power-saving mode, so it's always ready. The essentials kit goes beyond the tester itself, bundling everything required for comprehensive testing, including adaptors for various IEC lead types, a microwave leakage detector, a UK socket tester, and over 1,000 labels for asset tracking and compliance documentation.
Practical extras, such as a rugged carry case, an insulated screwdriver set, and access to online PAT testing training, make this kit particularly well-suited for new testers, electrical contractors, or facilities teams seeking an all-in-one, regulation-ready setup.
Whether you're working through classrooms, office spaces, or industrial units, the Martindale HPAT550 kit delivers professional-grade results with intuitive operation, bringing simplicity, accuracy, and convenience to every test.
