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 allrounder which will make your day-to-day work easier. testo 755-1 current/voltage tester, including batteries, measuring tips, measuring tip caps, calibration protocol and instruction manual. Measuring current with a voltage tester? The innovative testo 755-1 makes this possible – and is therefore suitable for virtually all daily electrical measuring tasks. The practical automated switch-on function and automatic measurement parameter detection also mean you can work more reliably than ever before with it.
