HT97 Digital Socket Tester - Regional Plugs

Get a digital starting point when investigating a compatible socket. The HT97-series plug-in tester brings supported wiring indications onto a display, with regional versions for US, EU and UK socket formats.

✅ See the wiring indication at the socket - The digital display presents the condition reported by the tester for further investigation when needed.

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

A Useful Starting Point for Socket Checks

When investigating an outlet, a displayed indication gives you a result to record and discuss rather than relying on how a connected appliance behaves. It remains one part of the investigation: a socket tester does not establish that the complete circuit is safe.

Choose HT97B for the US plug format, HT97D for EU or HT97E for UK, then confirm the marked operating range and instructions for that exact model. Plan any protective-device test around the connected equipment, because a successful trip can interrupt its supply.
