Non-contact voltage tester/cable break locator/current tester, cable tracer 12-1000V/48V 1000V

【Non-Contact Monopolar Voltage Detector】: Simply place the probe near a junction box, outlet, or power cord. You will know voltage is present when the probe lights up red and the pen beeps. 【Triple Alarm】: When voltage is detected, the voltage tester will sound an alarm, illuminate, and the bar graph will change. 【12~1000V AC】: Both standard mode (measuring range 48~1000V AC) and sensitivity mode (measuring range 48~1000V AC) measure 12~1000V AC. Both modes can be freely switched via the S button. [Example Application]: Detects the presence of voltage in the surrounding area and whether the power line is live. Differentiates between neutral and live conductors based on the alarm intensity, etc. Other highlights: built-in LED flashlight/low battery indicator/automatic shut-off/portable pen clip.
