The Testboy Profi III LCD is the top model in our proven Profi series. In addition to its practical one-handed operation, it impresses above all with its broad performance spectrum. It enables testing without finger contact and is also suitable for use on hybrid and electric vehicles as well as photovoltaic systems thanks to the highest safety level CAT IV 1000 V, which is almost unique for voltage testers. Voltage testing is even up to 1400 V DC. This top-of-the-range device is also characterised by its insensitivity and safe shadowing. Voltage is detected both optically and by vibration. No other standard two-pole voltage tester on the market has as many functions!
