The AEMC 275HVD Voltage Detector is designed to detect the presence of high voltage without physical contact. An eight position rotary switch selects the detection range. As the sensor is moved closer to the voltage carrying conductor its sensor head picks up the radiated electric field. Once the range threshold is reached, the buzzer sounds and a bright red warning light warns the operator of live conductors.

AEMC 275HVD Voltage Detectors are powered by three standard alkaline "C" cell batteries and can be used both indoors and out. A universal spline on the back-end facilitates attachment to any standard hot stick. A self-test position ensures that all circuitry and indicators are working properly before use.

Applications for the AEMC 275HVD Voltage Detector:

  • Non-contact detection of live voltages
  • Check and detect live high voltage cables
  • Find faults in cables
  • Check grounding equipment
  • Service neon lighting
  • Trace live wires
  • Check high frequency radiation
  • Detect residual or induced voltages

The AEMC 275HVD Voltage Detector ships complete with:

  • Shotgun adapter
  • (3) "C" cell batteries
  • Carrying case (padded)
  • Manual
