PicoLog CM3 is a compact and high-resolution 3-channel current data logger designed for monitoring and recording AC current consumption in buildings, machinery, and industrial systems. Supporting both single-phase and three-phase current measurements, it uses non-invasive current clamps to provide safe and accurate monitoring without interrupting electrical circuits. With 24-bit resolution, USB and Ethernet connectivity, support for multiple units, and powerful PicoLog software with cloud capabilities, the CM3 offers a flexible solution for energy monitoring, load balancing, and long-term power consumption analysis.
