Keithley 6221/2182A/E Delta Mode System, 220Vac Line Voltage

The Keithley 6221/2182A/E Delta Mode System is a complete low-level electrical test solution, integrating two industry-leading instruments: the 6221 AC + DC Current Source and the 2182A Nanovoltmeter. Together, they provide unmatched capability for ultra-low resistance, device characterization, and material research.

The 6221 offers precise DC and AC current sourcing from 100 fA to 100 mA, with programmable sine, square, and pulsed waveforms for advanced characterization. The 2182A Nanovoltmeter delivers 1 nV sensitivity with fast and stable readings. Using Keithley’s patented Delta Mode, the system synchronizes current sourcing and voltage measurements to cancel thermoelectric offsets, reduce noise, and maximize accuracy.

This “/E” variant operates on 220Vac line voltage, making it suitable for labs and facilities in regions requiring this power standard.
