Model No: testo 750-1 Part No: 0590 7501

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.

  1. Clear, patented all-round LED display
  2. In accordance with DIN EN 61243-3:2010 and CAT III
  3. Fibre-optics for optimum voltage indication
  4. Robust housing with ergonomic handle and anti-slip ring


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

Testo 750-2 voltage tester, including batteries, measuring tip protector, measuring tip caps, calibration protocol and instruction manual

Voltage-Tester - testo 750-2
Model No: testo 750-2 Part No: 0590 7502

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

  1. Clear, patented all-round LED display
  2. In accordance with DIN EN 61243-3:2010 and CAT III
  3. With practical torch for measuring point illumination
  4. Including RC trigger function and vibrating load buttons


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

Testo 750-3 voltage tester, including batteries, measuring tip protector, measuring tip caps, calibration protocol and instruction manual

Voltage Tester- - testo 750-3
Model No: testo 750-3 Part No: 0590 7503

Testo 750-3 voltage tester is the most high-performance model in Testo's convenient and reliable voltage tester family. In addition to the unique fibre-optic technology, the single pole voltage testing, the torch for measuring point illumination and the all-round LED display, it also has an LC display where the value currently being measured is shown

  1. Clear, patented all-round LED display 
  2. In accordance with DIN EN 61243-3:2010 and CAT III
  3. LC display showing the reading
  4. RC trigger function and vibrating load buttons


Testo 750-3 voltage tester is the most innovative voltmeter on the market. The clear all-round LED display with fibre-optic technology for ideal voltage indication can easily be read in any position. A second LC display also indicates the current reading. An anti-slip ring and the ergonomic shape of the handle also ensure you can work comfortably. The integrated torch helps with the illumination of dark measuring points. And the voltage tester is extremely durable thanks to the robust housing.

The testo 750-3 voltage tester is first and foremost suitable for determining voltage or de-energization on electrical circuits or systems. In addition, it can also be used to test continuity, measure rotating magnetic fields and test residual current circuit breakers via the RC trigger function. Vibrating load buttons ensure that trigger tests cannot be carried out accidentally
