Omega’s non-contact voltage testers take the risk out of testing for live wires. Just press the button on the hand-held tester and place the tip against a wire or in an outlet. If the alarm rings and the tester lights up, then the line is live. There’s no easier way to test wires that are passing through your work environment or application. Shop at Omega for the highest-quality non-contact voltage testers and get them for less.
