- Safety feedback: Visual and audible signals provide voltage level updates with a frequency-to-voltage correlation shown on an LCD percentage display, enabling continuous monitoring for maximum user awareness. - Reliable contactless measurement: NCV sensor technology with a highly sensitive inductive probe allows accurate voltage detection without direct contact for alternating current from 12 to 1000 volts. - Detailed evaluation: Sensitivity-controlled measurement with automatic voltage classification. A visual bar display enables immediate interpretation of readings across various low-voltage systems. - Safety innovation: Patented double-protection system with visual and audible alarms detects voltage fluctuations precisely and provides optimal personal protection in different electrical installations. Use scenarios: - Electrical installation and maintenance in residential or small commercial settings to verify safety before touching wires. - Panel checks and troubleshooting to detect voltage presence and fluctuations without disconnecting circuits. - Quick safety checks during installation of low-voltage systems such as lighting, sensors, or outlets to confirm safe conditions before work.
