This multifunctional tool features the function of NCV AC voltage detector, ambient temperature tester, / neutral wire discrimination and flashlight. With LCD screen for easy reading and compact size for easy operation, it can be widely used in electrical testing, car repairing and more applications.Non-contact AC voltage detection or insert the tester's probe into the outlet, with alarm buzzer function. And the LED flashlight ensures safety work in dark environments./ neutral wire discrimination: the tester's detection induction is strong when it's a wire, and the induction is weak or there is no induction signal when it's a neutral wire. range of AC voltage detection: low sensitivity mode (48~1000V)/ high sensitivity mode (12~1000V). It's recommended to use the low sensitivity mode for detection first.Powered by 2 AAA batteries (not included), with battery undervoltage indication. Without operation or voltage signal, it will auto shutdown in about 5 minutes to save battery.Material: plasticcolour: blackPackage Contents:1 x Voltmeter digital ammeterOnly the above package content, other products are not included.Note: Light reflection and different displays may cause the color of the item in the picture a little different from the real thing. The measurement allowed error is +/- 1-3cm.
