H285 HD High Voltage Detector


H285 HD High Voltage Detector is primary used to detect the presence of an alternation field. It shows identification of AC voltages. 285 HD has a large LCD that is housed in an ABS enclosure. 285 HD can be attached to the cable by a large metal clip and can be secured with a cable tie. The high voltage detector senses the radiated magnetic filed surrounding the cable and shows a LIVE warning sign on the LCD.



  • Three different ranges of identification of AC voltage:
    - 285-A HD: 3~7 kV
    - 285-B HD: 6.6~11 kV
    - 285-C HD: 10~22 kV.
  • Large LCD will "flash continuously" for high voltage testing.
  • Physical contact with electrical conductors is not necessary when testing for live wires
  • The 285 HD senses the radiated field that surrounds live conductors.
  • Radiated field strength increases with voltage and decreases quickly with distance.
  • Continuous monitoring.
  • Easy to install. No batteries required.
  • Weight: Approx. 80g.
  • Safety standards: EN 61326-1. EN 55011. EN 61000-4-2. EN 61000-4-3.


  • Identify and check live cables.
  • Check live wires at high voltage.
