Mastfuyi FY18D Non-contact AC Voltage Tester with Dual Range 12V-1000V/ 48V-1000V Multifunction NCV AC Voltage Measuring Pen Live/ Neutral Wire Ambient Temperature Tester with LCD Display/ Flashlight/ Alarm Buzzer

features the function of NCV AC voltage detector, ambient temperature tester, live/ 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.
Features:
Non-contact AC voltage detection or insert the tester's probe into the power outlet, with alarm buzzer function. And the LED flashlight ensures safety work in dark environments.
Dual 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.
Live/ neutral wire discrimination: the tester's detection induction is strong when it's a live wire, and the induction is weak or there is no induction signal when it's a neutral wire.
Ambient temperature: the device can measure the temperature of the surrounding environment, not the water or food temperature. Unit selectable: ℃/ ℉.
LCD screen greatly enhances the reading experience and makes it easy to read. One hand easy operation, very convenient to use. Compact and lightweight, portable to carry.
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.
