Martindale Electric has unveiled two new handheld Portable Appliance Testers (PAT) – the HPAT550 and HPAT650. Compact, easy to operate and feature-rich, the new testers are designed to simplify PAT testing while maintaining full compliance with testing requirements for Class I and Class II appliances.
Replacing the HPAT400, HPAT500 and HPAT600 the new models are built for portability and convenience. They offer one-button automatic testing and a clear PASS/FAIL indication, backed by measured values shown on a high-resolution colour display. These features, combined with USB-C fast charging and a lightweight, rugged design, make the HPAT series ideal for engineers conducting routine testing on the move.
The HPAT550 and HPAT650 deliver all the essential tests needed to verify the safety of electrical appliances. Both instruments include an IT-safe 200mA earth continuity test, selectable insulation resistance testing at 250V and 500V, and a dedicated test mode for IEC power leads. The 250V insulation test option ensures compatibility with surge-protected devices, giving testers greater flexibility across a wider range of applications.
With a simple interface and logical test sequencing, the HPAT series has been developed to reduce user error and increase efficiency, particularly for high-volume PAT environments. The HPAT550 features fully automated testing modes for quick and consistent results.
For those needing more advanced features, the HPAT650 steps up with additional capabilities. The unit includes onboard memory for storing up to 100 test results with on-screen recall, allowing testers to keep track of their testing without external devices. Single test execution mode enables users to carry out individual tests manually, while user-adjustable test limits cater for appliances with longer supply leads or non-standard requirements.
The HPAT650 also includes a substitute leakage test feature for checking earth leakage at reduced voltage, an essential addition for sensitive electronic equipment where powered testing is impractical or not permitted.
Both models feature an intuitive user interface with context-sensitive help screens, making them accessible to both seasoned professionals and those new to PAT testing. The robust yet compact construction ensures durability in challenging site conditions. Both testers can complete a significant number of tests on a single charge with an auto power-down feature to extend battery life even further.
The HPAT550 and HPAT650 are supplied with everything needed to begin testing straight out of the box. Each kit includes a TL67 earth bond probe, EX322 IEC adaptor lead, TC57 carry case, and a USB-A to USB-C charging cable, alongside a verification certificate and operating instructions.
