Advantages:

  • > Reliable continuity tester

The Testboy 2 was the best-selling continuity tester in Germany. The Testboy 20 Plus is the logical further development. Thanks to the contactless voltage sensor, it detects AC voltages through the insulation. Defective extension cables or multiple plugs are detected precisely and in a matter of seconds. The electronics also enable single-pole phase detection.
