The first voltage tester with current measurement is here: the testo 755. You can test electrical circuits or systems for voltage or de-energization, measure flow of current or current consumption and carry out continuity tests using a single instrument. In the process, the testo 755 voltage tester detects and selects all the electrical parameters automatically: you can just start measuring – without any switching on or selection.
The measuring tips, which can be quickly and simply exchanged, are also particularly user-friendly. This means you do not need to replace the whole instrument straight away in the event of damage. Just as practical: the integrated torch for illuminating dark measuring points.
Compared to the testo 755-1, the testo 755-2 has an increased voltage range of up to 1,000 V and enables rotating magnetic field measurement along with single pole voltage testing to determine quickly whether conductors are live.
