TESTBOY 114. Non-contact voltage tester for detecting electrical cable breaks. From low voltage 12 Volt AC usable.


The TESTBOY 114 is a high-quality, non-contact voltage tester with optical signaling and vibration alarm.

This tension tester is ideal for detecting invisible cable breaks in the electrical cable or to determine which LED in the fairy lights provides the interruption. Above all, however, the Testboy 114 is an ingenious tool for reducing NF electrosmog by detecting incorrectly plugged power plugs into the socket.

TESTBOY 114 is a voltage tester for detecting cable interruptions. Find the correct insertion direction of the cable?


The Testboy 114 convinces on the whole length. Both the type of signal message as well as the wide measuring range between 12 and 1000 volts AC (AC) make this a valuable tool in electrical problem detection. We are convinced that such a non-contact voltage tester should not be missing in any household or tool bag, so much so that the Testboy 114 makes everyday life easier when looking for an electrical fault.

There are several models from TESTBOY. We chose a high quality model that has the widest range of application and the optimal signal message upon detection of the error. To detect the TESTBOY 114 uses a capacitive measuring method (measurement based on change in the electric field). The measurement takes place without contact and is therefore simple, fast and effective. An invisible cable break in the extension cable can be located within a few seconds to the centimeter. The advantages of Testboy 114 are:

  • capacitive measurement procedure
  • measurements from 12 V
  • LED torch
  • optical indication (red luminous)
  • vibrating indication

Enormous measuring range of the Testboy 114 allows a wide application

The application can not be simpler. Simply slide along the power cable with the Testboy 114; if the signal is interrupted, the interruption in the electric cable is found. The detection starts at 12 volts and reaches 1,000 volts. Thus, with just this one voltage tester, just about anything electrical in the home can be checked. The Testboy 114 was designed to detect interruptions, but we see a major advantage in detecting and avoiding electric fields with this voltage tester. Thus, the correct insertion of the power plug alone can significantly reduce the automatically produced electric field.

Examples of possible applications of the Testboy 114

  • A loose contact in the electric cable from the household appliance. Depending on how the cable is twisted or bent, this will work with a connected home appliance. With the Testboy 114 the cable break is found immediately.
  • An LED in the fairy lights is defective. This leads to the fact that the whole fairy lights no longer work. With the Testboy 114, the spot with the defective LED is found immediately, replace LED, done.
  • Incorrect plugging the power plug produces an unnecessarily high electric field. With the testboy 114, the optimal insertion direction can be found.
