Description
The TES-3079M AC 1000A Clamp Meter is a highly versatile, 10-in-1 electrical testing tool designed for professional electricians, industrial engineers, and technicians. It combines True RMS current measurement with a dual display for simultaneous readings of multiple parameters. Capable of measuring AC/DC voltage, AC current, inrush current, mA, resistance, capacitance, diode, and temperature, it provides a complete solution for electrical diagnostics and troubleshooting. Its auto and manual range selection simplifies measurement tasks for both simple and complex electrical systems.
The meter also supports power analysis functions, including True Power (kW), Apparent Power (kVA), Reactive Power, Horsepower (HP), phase angle, and power factor. The phase sequence indication and frequency measurement allow verification of single- and three-phase systems. With features such as auto power-off, TRMS reading, fast sampling, and high-resolution display, this clamp meter ensures accuracy, convenience, and safety in field and lab operations. Its robust design allows continuous use in demanding environments, while overload protection up to 600V AC/DC and 1000A AC prevents damage during high-current testing.
