DC Precision Current Sources
DC Precision Current Sources provides precise and very stable output currents from 3 A to 10,000 A. The 6623A-PCS Series provides the best uncertainties of any DC high current sources (i.e. < 5 ppm of precision and stability at 1000A). In addition this Series is modular and initial output currents can be expanded at any time.

SparkFun Current Sensor Breakout
INA169
The INA169 is a “high-side current monitor,” which means that you place a resistor (a “shunt resistor”) on the positive power rail and the INA169 measures the voltage drop across that resistor. The INA169 outputs a small current based on the measured voltage drop. If you place a resistor from the output of the INA169 to ground, you can measure the voltage at the output.
