The Testo 755-2 is a professional current-voltage tester designed for electricians who need a wider voltage range and more flexibility on-site. It builds on the trusted 755-1 with extra features like single pole phase testing and expanded voltage measurement up to 1,000 V AC, ideal for industrial or 3-phase systems.
With automatic detection of measurement parameters, you can test voltage, current, resistance and continuity without changing settings.
How does the Testo 755-2 make life easier on-site?
It senses what you’re testing, voltage, current, resistance and selects the right mode automatically. Plus, it turns on by itself when you touch a circuit. No dials, no switches, no wasted time.
Built for Industrial & Commercial Use
If you're working in environments with higher voltages, three-phase systems, or complex fault-finding jobs, the Testo 755-2 gives you:
Voltage testing up to 1,000 V AC / 1,500 V DC
Single-pole phase detection
Non-contact voltage indication
Replaceable tips to keep your tester site-ready
