TPI 50 Non-Contact AC Volt Tester

The TPI 50 helps you check for AC voltage without undoing terminals or removing covers. Use it to make a quick go or no go check before you handle a conductor.

Move the TPI 50 along an insulated wire, or place the plastic tip near a socket, fuse, junction box, or switch. When voltage is present, it gives a clear signal so you can act with more care.

Fast checks with clear alerts

With TPI 50, the tip LED glows bright red and an audible buzzer sounds when it senses AC voltage. This pairing reduces guesswork when you are working in busy plant rooms or noisy areas.

Useful support for basic fault finding

As you trace a run, TPI 50 can help you spot where the indication stops, which can point to a break in a circuit or wire. That makes it handy for first-pass checks during service work and routine maintenance.

Keep TPI 50 in your kit for HVAC, irrigation, plumbing, and vending tasks where you need a fast presence check. Because it is always on, you can move between test points with fewer pauses.

Key Features

  • Confirms AC voltage presence without disconnecting conductors
  • Supports quick go or no go checks during call-outs
  • Gives an audible buzzer to signal a live AC source
  • Uses a bright red glow at the probe tip for clear feedback
  • Helps reduce unnecessary contact with live electrical points
  • Works well when checking wall sockets in the field
  • Fits routine checks on fuses, switches, and junction boxes
  • Helps you move faster when there are many points to test
  • Suits service and maintenance workflows across trades
  • Designed for checking insulated wiring during inspection work
  • Useful as a first check before deeper electrical testing
