A Klein voltage tester is a device used to detect the presence of voltage in an electrical circuit. It is a valuable tool for electricians and other professionals who work with electricity, as it can help to prevent electrical shock and other accidents.
Klein voltage testers are typically small, handheld devices that are easy to use. They have two probes that are inserted into the circuit being tested. If voltage is present, the tester will light up or sound an alarm. Some models of Klein voltage testers also have a display that shows the voltage level.
