What to focus on when choosing a voltage tester
Voltage measurement range
Determines the extent to which a tester is able to measure A/C or D/C electric current. Testers with a higher range offer more measurement options.
under 250 V - suitable for active and passive electrical network components. Ideal for electronics assembly.
over 250 V - allows you to measure a car battery or even a power outlet at home.
Ergonomics
A properly shaped handle ensures easy handling. Rubber grip also helps you hold the device safely when testing voltage.
Useful features
Display - shows current readings and other information.
IP64 protection - offers protection against water and dust. These testers are more versatile in their use.
Indicators - low battery warning, voltage type, polarity, or phase.
