Milwaukee Dual Range Voltage Detector is a versatile tool designed for both commercial and residential electrical applications. This advanced voltage detector features an expanded sensitivity range of 10-49V AC, allowing it to detect low-voltage systems such as LED lighting, fire detection systems, HVAC controls, and security systems, in addition to the standard 50-1000V AC range. It automatically differentiates between the two voltage ranges using uniquely colored LED indicators and audible tones, providing clear and accurate feedback. Lightweight and cordless, this detector is for electricians, low-voltage technicians, and facilities maintenance professionals who need a reliable and easy-to-use voltage detection solution.
