Neulog's current sensor can be used to measure the current in parallel or series branches of low voltage AC and DC circuits and to investigate the dependence of the current flow through components on the voltage across them. With its 4 mm plugs it can easily be connected into electric circuits. Additional accessories, such as USB, Wi-Fi, or battery modules, are required for operation depending on the device (PC, tablet, viewer) used to receive readings from the sensor.
