Clamp Meters are versatile electrical tools designed for measuring current without disconnecting the circuit. They feature a hinged jaw that clamps around a conductor, enabling safe and efficient AC/DC current measurements, voltage, resistance, and continuity. Ideal for industrial applications, these meters are essential for electricians, technicians, and engineers working on live systems. Models often include advanced features like true RMS, data logging, and Bluetooth connectivity for enhanced diagnostics. Common brands include Fluke, Hioki, and Klein Tools, offering rugged designs for demanding environments.
