T500HVD Non-contact AC high voltage detector with hot stick

The Model T500HVD 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.The Model T500HVD is powered by three standard 9V cell batteries and can be used both in and out-of-doors. 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.



  • Non-contact detection of live voltages
  • Check and detect live high voltage cables
