Non Contact Voltage Tester AC 12-1000V Voltage Detector

Dual Range AC Voltage DetectionThis voltage tester features dual sensitivity ranges to detect both low voltage (121000V) and high voltage (481000V), making it highly versatile for residential, commercial, and industrial electrical work. With a single button, you can smoothly switch between modes to adapt to different testing environments and accuracy requirements. | Non-Contact Voltage TestingDesigned for safe and efficient operation, this non-contact voltage tester allows you to check for live electricity without touching wires or terminals directly. Simply place the NCV probe near outlets, cables, or junction boxes, and the tool will immediately trigger light and audible buzzer to alert you of hazardous voltage, greatly reducing the risk of electric shock. | High & Low Sensitivity Ideal voltage tester allows automatic selection of two kinds of sensitivity (High,low). Live/Neutral wire distinguish at close range. | Auto Power OffThe integrated bright LED flashlight supports reliable use in dimly lit spaces, attics, basements, or tight electrical boxes. For energy efficiency and extended battery life, the tester automatically shuts off after 3 minutes of inactivity or when no voltage signal is detected. | Low Battery WarningA clear low battery indicator activates when voltage falls below 2.5V, preventing sudden power loss during critical tasks. This tester with double insulation for professional-grade safety, stability, and long-lasting durability.Safety level-Class II laser, <1mW power output
