Conductivity indicates the TDS or total dissolved solids affecting water quality, often used in the testing of water or for process control. Conductivity or electrical conductance increases with dissolved salts but does not identify specific water pollution, only indicating general water quality. The robustness of the technology ensures reliable on-line process control. Portable conductivity instrumentation allows testing of water and determination of general water quality for surface water and environmental applications.
The WTW IQ Sensor Net system is a multiple sensor input controller, accepting the Tetracon 700 IQ sensor which uses a four electrode design suitable for waste water monitoring. The Chemitec 50 Series is also a digital multiple sensor input platform which can accept the competitively priced S411 DIG digital sensor, providing two-electrode conductivity measurement.
