I'm interested in sourcing water quality sensors and display units to monitor various parameters, including COD, BOD, TSS, pH, TOC, and DO. The ideal sensors should offer reliable and accurate readings, suitable for both industrial and environmental applications. Additionally, I'm looking for options that provide user-friendly interfaces and robust data logging capabilities. If you have any product recommendations or catalogs, please send them my way.
