Stream Real-Time Diagnostic Footage and Navigate Deep Cavities with Wireless Precision

The Klein Tools ET20 is a portable wireless diagnostic borescope engineered to transmit high-resolution video and images directly to iPhone and Android smartphones via an internal WiFi signal. Featuring a 6-foot armored gooseneck cable and a slim 0.35-inch camera head, this tool allows for the close-quarters inspection of complex electrical conduit runs, plumbing lines, and structural wall cavities. The system utilizes an integrated rechargeable lithium-ion battery providing 5.5 hours of continuous runtime alongside a ruggedized 10-foot drop-protected housing built for the jobsite.

Best Used For:

  • Electrical Junction Inspections: Locating missing pull-strings, hidden wiring connections, and structural blockages deep inside narrow partition walls.
  • Plumbing Line Assessments: Documenting internal corrosion, wastewater clogs, and line cracks safely inside submerged or damp pipe environments.
  • HVAC Duct Troubleshooting: Navigating complex sheet metal ductwork networks to verify damper positions and inspect internal heat exchangers.

Key Performance & Safety Features

  • Secure Wireless Streaming: Built-in internal WiFi chip broadcasts a dedicated video feed to smart devices from a distance of up to 30 feet.
  • Armored Gooseneck Core: Robust 6-foot cable retains its preset structural shape when reaching overhead into deep industrial machinery or drops.
  • Submersible Optical Head: Slim 0.35-inch lens features an IP67 waterproof certification for clear imaging within flooded lines and sewer stacks.
  • Tunable Matrix Lighting: Six integrated white LEDs with adjustable output controls eliminate hot-spot glare on reflective steel or copper surfaces.
  • High-Impact Structural Body: Double-molded polycarbonate and ABS shell delivers a certified 10-foot drop protection rating for high-stress workspaces.
  • App-Driven Data Transfer: Connects to the proprietary mobile application to instantly record, archive, and email digital diagnostic proof directly to clients.
