Description

Features:
Wide-Ranging Electrical Testing Tool: This industrial-grade digital voltage tester detects voltages from 12V to 300V AC. It supports multiple functions including AC voltage measurement, non-contact voltage sensing (NCV), battery polarity detection, live/neutral wire identification, continuity testing, and data hold, making it a versatile tool for electricians and DIY enthusiasts.
Convenient Continuity & Battery Testing: For continuity checks, simply press and hold the "Continuity Test" button, hold 1 end of the wire, and touch the probe to the other end. To test battery polarity, hold the same button, touch the battery's negative terminal with your hand, and place the probe on the positive terminal—ideal for quick diagnostics.
Smart NCV Voltage Detection: The non-contact voltage sensing feature alerts you safely when approaching an AC voltage source. For weak signals, the beeper sounds intermittently with "–L" displayed. For strong AC voltage, the beeper emits a continuous alarm, the screen turns red, and shows "–H" for clear, safe identification.
Long-Lasting & User-Friendly Operation: Powered by a built-in 3.7V/220mAH rechargeable lithium battery with USB charging. The tool includes an auto-shutdown function to save power after 15 minutes of inactivity, plus a practical flashlight—activated by long-pressing the "0" button—for working in dark environments.
Clear AC Voltage Measurement & Display: In AC voltage measurement mode (activated by long-pressing the "Voltage Test" button), simply touch the probe to an AC conductor to see the accurate voltage value on the clear digital screen. Combined with data hold and bright LED indicators, it ensures reliable and easy-to-read results every time.
