6220/6221 DC and DC/AC Current Sources

Product Description

In our effort to bring our customers the highest level of precision measurement capabilities, Fluke Calibration is proud to offer these precision metrology grade products from Keithley Instruments. Renowned as a leader in low-level precision electrical measurements, these selected Keithley products present an opportunity to help you further reduce uncertainties in your lab.

The 6220 DC Current Source and Model 6221 AC and DC Current Sources combine ease of use with exceptionally low current noise. High sourcing accuracy and built-in control functions make the Models 6220 and 6221 ideal for resistance measurements using the delta mode, pulsed measurements and differential conductance measurements. These 622X sources, when linked to the Model 2182A Nanovoltmeter, provide control with excellent measurement results for low-value, low-noise resistance measurements.
