Source Measure Unit

A source measure unit (SMU) combines precision voltage/current sourcing with simultaneous measurement in a single instrument, replacing separate power supplies and multimeters. SMUs excel at I-V characterisation of semiconductors, LEDs, solar cells, batteries, and nanomaterials, with resolution down to femtoamp and microvolt levels. They are widely used in semiconductor fabs, university research labs, and quality assurance departments. Our range includes single and multi-channel models from Keithley and other leading manufacturers, supporting applications from basic component testing to complex parametric analysis.
