The two-pole voltage tester is the standard tool of every qualified electrician: use it to verify the absence of voltage in line with the five safety rules and in compliance with DIN EN 61243-3. Testboy voltage testers such as the proven Profi series impress with their robust design, clear indication via LED or LCD and additional functions such as continuity and phase rotation testing.
