Reliable online monitoring of industrial wastewater

CA72TOC determines the total organic carbon (TOC) content in a number of industries. It measures reliably and accurately even in heavy duty applications with high loads of salt, fat or fibers. The reliable detection of product losses increases the process yield and saves money every day. Designed for long-term stability and highest availability, the CA72TOC offers maximum operational safety of your plant. Clear diagnostic messages actively support your predictive maintenance strategy.
