The Genuine Extech DV25 Dual AC Voltage Detector is a reliable and efficient tool for detecting AC voltage up to 1000V. With both light and sound alarm functions, this detector provides a clear indication of the presence of voltage. Designed by the trusted brand Extech, this dual voltage detector is essential for electrical testing and inspection in various industrial and commercial settings.
Detects AC voltage when there is no voltage anywhere nearby. Cannot be relied upon to indicate whether a cable is live. Bought another brand with adjustable sensitivity, for half the price, that works perfectly.
