Non-Contact AC Tester Pen - Standard or Voice Option

Check for AC electric-field indications without direct contact with exposed metal. Choose the standard LED/buzzer tester or the version with English voice prompts.

✅ Notice a signal in more than one way - LED and buzzer feedback provide visible and audible indications.

✅ Choose sensitivity for the check - Low mode covers 48-1000 V AC, while high mode extends the stated lower limit to 12 V AC.

✅ Use spoken prompts on the voice version - The separate voice option adds English announcements alongside LED and buzzer feedback.

AC Detection Only, Not DC or Continuity

The tester senses 50/60 Hz AC fields. It is not for 12 V automotive DC circuits, batteries, resistance or continuity. Nearby wires, shielding, insulation and static can affect indications.

A missing indication does not prove a circuit is safe. Follow the instructions, inspect the tool and verify its operation before use. Two AAA batteries are required and not included.

Choose T03A for LED/buzzer feedback or T03B for the added English voice feature. Tighten the battery cap fully and fit the cells with the correct polarity.
