AC and DC current source for delta mode, differential conductance and pulse measurement. Ovento Systems carries the Keithley 6221 as used and refurbished stock within our source measure units & electrometers range, sourced through equipment liquidations, service company fleet upgrades and OEM trade-ins across North America and Asia.

Source and measure functions are exercised across each range against a reference standard, and low-current performance is confirmed rather than assumed. Stock is held in Plano, TX and normally despatches within one business day of order confirmation. Most enquiries on this model come from semiconductor test engineers, materials research groups and photovoltaic laboratories. If you need several, or need them matched, say so on the request and we will quote as a set.

What is included with the 6221

What ships is listed explicitly on your quote rather than implied: the instrument, any accessories physically present, and the condition grade. If something you need is missing, we will tell you before you order rather than after. If you are completing an existing kit, tell us the part numbers you are missing and we will check accessory stock against them.

Buying this class of instrument used? Buying a used oscilloscope: what actually matters covers what to check before you pay.
