The Cathodic Protection Remote Data Acquisition Module is a monitoring device that automatically collects and transmits cathodic protection data from buried steel pipelines and storage tanks. Installed in test posts along pipelines, it connects to reference electrodes and polarization probes to measure key parameters such as ON/OFF-potential, natural potential, and AC interference. Data is sent to the cloud via 4G, NB-IoT, or LoRa and accessible through PC or mobile apps, enabling digital and intelligent pipeline management.
