Electric tester pen with a buzzer alarm is a non-contact voltage detector that signals the presence of electricity with
a buzzer sound and flashing light. These pens are designed for safety and convenience, allowing users to test for
live wires in a variety of applications like power cables, outlets, and fuses without direct contact. Some models also
feature additional functions like a built-in LED flashlight.
This innovative voltage tester pen combines audible and visual alerts for enhanced safety during electrical testing.
The integrated buzzer emits a loud tone when live voltage is detected (typically ≥ 70V), while the bright LED indicator illuminates
to confirm contact. The non-contact design allows for quick voltage detection without direct wire contact, with a sensing range
of 90-1000V AC.
