Martindale EZ165 Socket & Non-Trip Earth Loop Tester

Martindale EZ165 Socket & Non-Trip Earth Loop Tester

Advanced Socket Testing for Electricians and Maintenance Engineers

The Martindale EZ165 is designed for electricians, electrical contractors, appliance service engineers and maintenance technicians who need a quick and reliable way to verify socket wiring and earth integrity before carrying out electrical work. More than a standard socket tester, the EZ165 detects 28 socket wiring fault conditions, checks mains voltage levels and performs a non-trip earth loop impedance test, helping identify potentially dangerous earthing issues quickly and safely.

Designed for Safer Electrical Inspections

The EZ165 verifies earth wiring by measuring earth loop impedance and displaying results across six ranges from less than 1.7Ω to 500Ω. This allows users to assess whether the earth path is suitable for protective devices to operate correctly during fault conditions. Red and green LED indicators provide fast identification of socket polarity and wiring faults, while the built-in fault chart helps diagnose issues efficiently on-site.

Why choose the Martindale EZ165?

Unlike basic socket testers that only indicate the presence of an earth connection, the EZ165 provides valuable earth loop impedance information to help identify potentially unsafe installations. Recognised by the Health & Safety Executive as an Advanced Socket Tester, it is ideal for electrical safety checks before servicing, maintaining or installing mains-powered electrical equipment. The EZ165 also replaces the popular Martindale EZ150, offering enhanced functionality in a compact and easy-to-use design.
