Non-contact voltage tester and faulty cable locator – 12 to 1000 V current detector for electrical installations

【Monopolar Non-Contact Voltage Detector】: Simply place the probe near the junction box, socket, or power cord. You will know voltage is present when the probe lights up red and the pen beeps.【Triple Alarm】: When voltage is present, the voltage tester will emit an audible and visual alarm, and the bar graph will change.【12~1000V AC】: Standard mode (measuring range 48~1000V AC) and sensitivity mode (measuring range 12~1000V AC). Both can be freely switched via the S button. [Example Application]: Detects if there is voltage in the environment and if the power line is live; distinguishes between the neutral and live wires by the alarm intensity, etc. Other highlights: built-in LED flashlight/low battery indicator/automatic shut-off/portable pen clip.
