Martindale Electric further strengthens PAT tester range with the HPAT425

April 28, 2026

Safety and test equipment specialist, Martindale Electric, has launched the HPAT425 handheld PAT/EET tester, which can be used for testing all types of portable appliances and is specifically built for ease of use with one-button automatic testing.

The new HPAT425 is designed for clear, simple and automatic pass/fail testing of Class 1 & Class II appliances and IEC power leads. The unit is compact and lightweight for maximum portability and features a USB-C charging port for fast on-the-go charging.

The large, high-contrast greyscale display is ideal for testing in varying light conditions. Plus, the HPAT425 features both 500V and 250V insulation test options – ideal for surge-protected devices – as well as an IT-safe 200mA earth bond test.

Replacing the popular Martindale HPAT400 model, the improved HPAT425 offers everything needed to begin testing straight out of the box. This includes a TL67 earth bond probe, EX322 IEC adaptor lead, TC57 carry case, and a USB-C charging cable, alongside a verification certificate and instruction manual.

A comprehensive range of optional accessories is also available, including adaptors for testing appliances and equipment fitted with 3-phase plugs. Also, ideal for the first time user, the optional Martindale PATKIT1 starter kit includes 1,000 pass labels, 200 fail labels, PAT logbook, and a set of IEC cable adaptors.

The HPAT425 complements the recently launched advanced and feature-rich HPAT550 and HPAT650 handheld testers, making the all-encompassing HPAT series a more adaptable solution for engineers and contractors conducting routine testing on the move. It delivers all the essential tests needed to verify the safety and compliance of electrical appliances across a wider range of applications.

All Martindale Electric PAT testers are built to meet the latest safety standards. The testers are designed and supported in the UK, with Martindale’s well-known commitment to reliability and customer service.
