400A AC DC Current Clamp

The Sealey 40A / 400A AC / DC Current Clamp is a professional diagnostic tool designed for measuring current draw from vehicle electrical components without breaking into the circuit. Ideal for automotive technicians and electricians working with multimeters, this versatile clamp meter offers non-invasive current testing capabilities for both AC and DC circuits. This current clamp features dual range settings of 40A and 400A, providing accurate measurement across a wide spectrum of automotive and electrical applications. The Ø28mm clamp opening is particularly suited to testing wire bundles and larger conductors up to Ø20mm diameter, whilst the output is optimised for use with standard multimeter voltage ranges (200mV or 400mV). Fitted with standard 4mm banana plug connectors, the unit integrates seamlessly with most professional multimeters and can also be adapted for use with oscilloscopes via a suitable BNC converter. Supplied complete with a 9V battery and protective storage pouch, the clamp meter is ready for immediate use. The LED low battery indicator ensures reliable operation, whilst the compact dimensions (175mm x 70mm x 38mm) and 240g weight make it highly portable for mobile technicians. With an impressive 80-hour battery life from alkaline cells, this tool delivers consistent performance across demanding workshop environments.
