Martindale HPAT425 Handheld PAT Tester

The Martindale HPAT425 Handheld PAT Tester gives users a compact way to test portable appliances. It supports automatic pass or fail testing for Class I, Class II, and IEC power leads. Because it uses simple one-button testing, it suits users who need fast checks with clear results.

This handheld tester keeps site work simple and portable. Its small body makes it easy to carry between rooms, offices, workshops, and test areas. In addition, the large high-contrast greyscale display helps users read results in changing light conditions.

Simple automatic PAT testing

The Martindale HPAT425 Handheld PAT Tester offers automatic test routines for common appliance safety checks. It can test Class I appliances, Class II appliances, and power leads. Therefore, users can complete routine checks without complex setup steps.

Selectable 250 V and 500 V insulation test options help users match the test to the appliance. The 250 V option is useful for surge-protected devices. Meanwhile, the 500 V option supports standard insulation testing where suitable.

Portable design with USB-C charging

The Martindale HPAT425 Handheld PAT Tester uses USB-C charging for easy power support during mobile work. Its rechargeable battery supports fast charge use and helps reduce the need for spare batteries. As a result, users can keep the tester ready for regular jobs.

A 200 mA DC earth bond test supports IT safe earth continuity checks. The tester also includes fixed pass limits for earth continuity and clear pass or fail indication. With a two-year warranty and verification certificate included, the Martindale HPAT425 Handheld PAT Tester offers a practical replacement for the HPAT400.
