optek C8000 converter performing 8 different measurements simultaneously: UV-280, UV-300, 2x Conductivity, 2x pH, and 2x Temperature

C8000 Universal Converter

Multi Channel Photometric and Electrochemical Converter

Multi channel converter for all optek photometric and conductivity sensors and electrochemical pH electrodes. Flexible configuration of sensors, measuring ranges, units and product specific setups make the C8000 converter series a powerful device in process monitoring in both conventional and single-use systems.
