The Current Probe can be used to measure currents in low-voltage AC and DC circuits or for electrochemistry experiments.


The Current Probe measures DC and low-frequency AC currents up to 600 mA. Use Current Probes in combination with Differential Voltage Probes to investigate Ohm’s Law and explore series and parallel circuits. The 0.1 Ω shunt resistor minimizes changes to your circuit. If currents will exceed 1 A, use the High Current Sensor.
