HT97-Series Digital Socket Tester

Get a direct digital starting point when investigating a compatible socket. The HT97-series plug-in tester brings wiring indications and model-specific protective-device test functions to one display.

✅ Identify indications that need further investigation - The socket display helps you see the wiring condition reported by the selected tester.

✅ Check the supported protective-device response - The corresponding RCD or GFCI function provides a separate test for the appropriate installation.

Choose the Tester for the Socket

Match the regional model, plug and marked operating range before use. HT97B, HT97D and HT97E are different selections; RCD and GFCI test requirements should not be treated as interchangeable.

Read the exact model's instructions before planning a test, especially where tripping a protective device would interrupt connected equipment. A socket indication is not a complete electrical safety assessment; have faults investigated by a qualified person.
