testo 750-2 - Voltage tester

0590 7502
  • Clear, patented all-round LED display
  • In accordance with DIN EN 61243-3:2011 and CAT III
  • With practical torch for measuring point illumination
  • Including RC trigger function and vibrating load buttons
  • With the testo 750-2 voltage tester you can test electrical systems and equipment reliably and easily for voltage or de-energization thanks to the all-round LED display and unique fibre-optic technology. Compared to the testo 750-1, it is also suitable for single pole voltage testing to determine quickly whether conductors are live.
    The testo 750-2 voltage tester means you can work more conveniently than ever before. Its clear, patented all-round LED display can easily be read in any position and indicates the presence of voltage clearly and distinctly with large fibre-optic illuminators. It can be held securely in your hand thanks to the deep-seated anti-slip ring and the ergonomic handle. You can easily illuminate dark measuring points using the integrated torch. The robust housing makes the voltage tester extremely durable.

    In addition to determining voltage or de-energization on electrical circuits or systems, the testo 750-2 voltage tester is also suitable for use as a continuity tester and for rotating magnetic field measurement. It also has an RC trigger function for testing residual current circuit breakers. Vibrating load buttons ensure that trigger tests cannot be carried out accidentally.
