Keithley 2401 Low Voltage SourceMeter

The Keithley 2401 Low Voltage SourceMeter® is a compact and versatile SMU (Source Measure Unit) that integrates a precision power supply, true current source, 6½-digit multimeter, and electronic load into a single instrument. With a voltage range up to 20 V and current capability up to 1 A DC / 3 A pulse, the 2401 is optimized for testing low-voltage devices and components where high accuracy and repeatability are critical.

Equipped with Keithley’s SourceMeter® architecture, it can source and measure both voltage and current simultaneously, simplifying workflows and reducing the need for multiple instruments. Its fast measurement speeds and wide dynamic range make it suitable for research, quality assurance, and production environments.
