ActiveFinder One
Work safely on electrical lines – in handy pen format

Description: This non-contact voltage tester provides an extremely high level of industrial safety by detecting existing alternating voltages. The device determines the polarity of L- or N-conductors, detects live cables from 50 VAC to 1000 VAC, and locates electrical voltages in cables, sockets, bulb sockets and fuses. Cable breaks can be effectively identified. Its compact design, highly visible LED indicators and clip make this an easy tool to use.

  • Contactless detection of live lines
  • Locates electrical voltages in cables, sockets, bulb sockets and fuses
  • Effective detection of line breaks in cables and wires
  • Efficient: one measuring instrument can be used for the entire building installation
  • Compact design with convenient clip, practical for shirt pockets and tool boxes
  • Clearly visible LED for indicating electrical voltages
  • Additional acoustic signal
