Stay safe with the KAIWEETS non-contact voltage tester. It detects both standard and low voltage, making it ideal for checking breakpoints. Equipped with an NCV inductive probe for AC voltage, it automatically recognizes and displays readings on a histogram. It emits multiple alarm signals through sound and light, with a percentage indicator showing intensity. It features safe double insulation and a high-voltage alert for voltages above 90V—the screen turns red, and a safety symbol appears. A bright LED flashlight provides visibility in dark environments. A low battery indicator warns when voltage drops below 2.5V. It supports automatic power-off after 5 minutes of inactivity. Its compact size and pen clip allow for easy attachment to clothing and convenient portability.
