The TP165X features a remote control design that allows for safe and easy testing of electrical installations in hard-to-reach areas. Its flexible cable and lightweight design make it ideal for use in confined spaces or at heights.

The probe is designed to measure insulation resistance up to 5000 MΩ and features a selectable test voltage of 50V, 100V, 250V, 500V and 1000V. It also includes an auto-discharge function that ensures the safe discharge of any stored energy after testing is complete.
