The Dual Range Non-Contact Voltage Detector with LED Work Light is designed to safely and accurately detect voltage in a wide range of electrical applications. Ideal for electricians, contractors, and maintenance professionals, this detector identifies live voltage without direct contact, improving safety and efficiency on the job.
Featuring an expanded sensitivity range, the detector can identify voltage levels that standard testers may miss. It automatically distinguishes between low voltage (12–49V) and standard voltage (50–1000V), providing clear, easy-to-read feedback. A yellow indicator signals low voltage, while a red indicator alerts you to higher voltage levels, allowing for quick identification.
Equipped with a bright, independently controlled LED work light, this tool enhances visibility in dark or confined work areas. Built for professional use, the detector offers an industry-leading CAT IV 1000V safety rating, ensuring reliable protection in demanding environments.
