Georg Fischer Signet (GFS) seeks to provide a sensor to measure the concentration of total active ions (TAI) in ultrapure water applications. Part of the sensor includes a novel algorithm, which compensates for shortcomings of the raw conductivity sensor output. The Georg Fischer Signet clinic team has improved the algorithm itself and has developed a real-time implementation which is compatible with the existing conductivity sensor hardware.
