Mastfuyi Smart Induction AC Voltage Tester Pen 48-1000V With NCV Sensor
The Mastfuyi Smart Induction AC Voltage Tester Pen FY18D is a compact, non-contact detector designed for professionals and DIY enthusiasts alike. It detects AC voltage in the range of 48–1000 V without touching live wires, helping you verify circuits quickly and safely. With a smart NCV sensor, a selectable L/H sensitivity switch, and audible/visual alarms, you can distinguish between live and neutral wires and even locate wire breaks with precision. The integrated LCD displays voltage status, ambient temperature (0°C–70°C), and a low-battery warning for easy, on-the-spot diagnostics.
Built for everyday field use, this pen-sized tester measures 160 x 23 x 26 mm and weighs just 74 g, making it ultra-portable for hard-to-reach panels. It runs on 2x AAA batteries (not included) and features a dual flashlight to illuminate dark spaces. An automatic 5-minute power-off helps conserve battery life when you forget to switch it off. The device is CE-certified and rated CAT III 1000V / CAT IV 600V for professional reliability in electrical installations. All electronic and mechanical equipment, devices and machines sold by InterCyprus to EU countries are CE certified and carry a two year warranty.
