testo 750-1 - Voltage tester

0590 7501
  • Clear, patented all-round LED display
  • In accordance with DIN EN 61243-3:2011 and CAT III
  • Fibre-optics for optimum voltage indication
  • Robust housing with ergonomic handle and anti-slip ring
  • Your reliable companion when it comes to testing electrical systems and equipment. The all-round LED display and unique fibre-optic technology mean the voltage indication can be seen clearly and distinctly from any position with this voltage tester. 
    In contrast to the standard voltage testers on the market, the testo 750-1 voltage tester has an extremely practical all-round LED display which can easily be seen in every work position and from any location. In addition, large fibre-optic illuminators show the presence of voltage clearly and distinctly. The deep-seated anti-slip ring, the ergonomic shape of the handle and the robust housing provide greater comfort when working. The robust design means the voltage tester is durable and reliable, even when used intensively.

    The testo 750-1 voltage tester enables voltage or de-energization on electrical circuits or systems to be determined reliably. The instrument meets the latest EN 61243-3:2010 voltage tester standard and has a safety specification according to CAT III. In addition, it is suitable for continuity testing and rotating magnetic field measurement.
