The new Copper Analyzer System from Electro-Chemical Devices (ECD) is designed with the new advanced T80 Universal Transmitter and precision S80 Intelligent pION Sensor. Together, they provide accurate and reliable measurement of copper for electronics manufacturing wastewater treatment processes. ECD’s S80 pION Sensor for copper uses a cupric ion electrode cartridge that measures the activity of “free” copper ions in solution in concentrations from 1.0 ppb to 6,300 ppm.
