Key benefits - Accurate contactless voltage testing across a wide AC range (12-1000V) using NCV sensor technology and stable inductive sensitivity, enhancing safety and versatility. - Real-time monitoring with visual and audio alerts plus a dynamic LCD percentage display, providing instant feedback through frequency-voltage correlation and risk-level color coding. - Precise testing with sensitivity adjustment and auto-voltage recognition, ensuring compatibility with low-voltage systems and an intuitive strength display. - Secure voltage testing with an over-voltage alert and a robust double-insulation structure, delivering enhanced safety and consistent performance during electrical inspections. Practical applications - Residential electrical work: quickly verify outlets, switches, and wiring without direct contact, reducing exposure to live circuits. - Commercial and industrial maintenance: conduct checks on control panels, distribution boards, and wiring connections to ensure safe operation. - On-site installation and commissioning: use during new installations or servicing to confirm voltage presence and levels before proceeding.
