Reliable contactless voltage tester with NCV sensor technology and a highly sensitive inductive probe for accurate detection in the 12-1000V AC range without touching live parts. Clear guidance for safe operation: visual and audio alerts, LCD percentage data, and the ability to correlate frequency and voltage patterns. Color-coded risk levels provide immediate and reliable safety feedback. Smart voltage analysis: adjustable sensitivity and auto-voltage recognition ensure seamless low-voltage compatibility. A bar-graph visualization shows voltage strength for quick, at-a-glance monitoring. Injury prevention system: over-voltage alert mechanism and a double-insulated build protect users and support a secure testing experience. Use scenarios: - Check outlets, switches, and wiring in homes or offices for quick safety verification. - Perform panel and distribution board maintenance in commercial or facility settings. - Conduct field checks on generators, motors, or control cabinets to ensure proper voltage conditions.
