Description: A reliable and fast voltage tester with the most commonly used nominal voltages. The device can be used to perform a single-phase test and a rotating field test including indicating the phase direction. The automatic continuity test sends an acoustic signal to the user. The device is suitable for the whole building installation and conducts a safety self-test over 50 Volt to ensure safe operation. The integrated torch lights up the testing area, which makes work in dark environments much easier. Moreover, the voltage tester operates in emergency mode without batteries and has a robust housing largely made of recycled plastic, making a valuable contribution to sustainability.
