Homdum Non Contact AC Voltage Power Detector INGCO VD10003 AC 12-1000V Electric Current Alert Sensor Tester Pen with LED Light and Sound Alarm mode compact pocket battery Live Line neutral line Multimeter

Non-contact AC Voltage measurement - probe type induction, plastic insulation, It will flash and beep when the device close to AC Voltage greater during the specified Voltage range without touching the measured object, to ensure the safety of the human body, more convenient monitoring.***Safely sound & light alarm - distinguish the live and Null wire through different frequency alarm sounds. The higher the voltage, the higher the audible alarm frequency and rate of flashing lights - great, even in noisy environments.***Accurately multi-ranging measurement - accurately detects AC Voltage ranging from 12V to 1000V, and distinguishes them into 3 Voltage levels (low, moderate, high). ncv sensitivity automatically adjusts from low, medium and high while indicating Voltage level with audible beep.***Low voltage indicator & LED light - The shining prompt of a low voltage LED and alarm can warn you to replace the battery in time, while the LED light allows operation even in a dark environment.***Auto power off - operated with 2 x 1.5V AAA batteries(not included), auto power off after no operation for 3 minutes to save energy. Lightweight, durable construction with convenient pocket clip, a perfect handy tool for electricians or daily use.***Non-Contact Voltage Tester, within 12-1000V AC, All Electric Appliances can be Tested by it, It not only tells you whether there is voltage or not, but also tells you if the voltage is high or low, Ideal for testing AC cables, circuit breakers, wall sockets, junction boxes, fuses, etc, It also acts as an emergency flashlight, which is especially useful in the dark area, Other Function include: Auto power-off, Low Battery Power Indication.
