High Voltage Testers

Why Choose AEMC® Instruments Non-Contact High Voltage Detector?

Your safety is our concern. We know it’s critical for you to have the ability to save lives by safely detecting high voltages. That’s why we offer our non-contact High Voltage Detector model 275HVD. The Model 275HVD detects the presence of voltages from 80V up to 275kV without physical contact. The detector instrument can be used both indoors and outdoors.

Reliable Safety Sensor Indicators

Our instrument offers a self-test function that works through an actual sensing circuit, it does not just turn on a light and buzzer.

As the sensor is moved closer to the voltage carrying conductor, its sensor head picks up the radiated electric field. Once the threshold is reached, a loud buzzer sounds and a bright red LED voltage indicator light that is visible from a long distance, alerts the operator of live conductors. A self-test feature ensures all circuitry and annunciators are working properly.

Hot Stick Attachment

A universal spline on the instruments back facilitates attachment to any standard hot stick. Our durable handle will not come loose at the end of the hot stick when flexed.


  • Works on unshielded cables only
  • Wide range of detection; finds 80V to 275kV; one instrument fits all applications
  • Eight switch selectable voltage sensitivity ranges
  • Lightweight, minimizes sway at the end of long hot sticks
  • Audible and visual indication of live voltage
  • Self-test position ensures that all system functions and indicators are working properly by energizing the complete system
  • Designed for use with hot sticks incorporating a shotgun adapter
