The first voltage tester with current measurement is here: the testo 755-1. 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 755-1 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.
The testo 755-1 current/voltage tester is a genuine all-rounder which will make your day-to-day work easier.
