Thermalox TOC-TN Analyzer

ESC 8024


TOC (Total Organic Carbon) is a measurement widely used in a number of industries to assess the organic contamination of water. In wastewater TOC concentrations of many thousands of ppm are often found. At the other extreme, low ppb TOC levels must be measured in the Ultra- Pure water used by Pharmaceutical, Semiconductor and the Power Generation industries.
Sercon has made important advances in its techniques for measuring TOC and TNb. Working with one of the world’s leading NDIR analyser manufacturers, it has dramatically increased the sensitivity of its CO2 detector. The Thermalox detector is now over twenty times more sensitive than its leading rival.
