The first voltage tester with primary current measurement was the testo 755-1. You can test circuits or systems to measure voltage or power interruption, measure current consumption, and perform short circuit testing tasks using a single device. During this process, the testo 755-1 current tester automatically detects and selects all electrical parameters: you simply turn it on and measure, without the need for selection or configuration.
The testo 755-1 tester is a genuine Testo device that will make your daily work easier than ever!
