Zetian - Model WDet-5000TOC -Total Organic Carbon Water Quality Online Analyzer
WDet-5000TOC Total Organic Carbon Water Quality Online Analyzer is a new kind of automatic TOC online analyzer. Based on our Injection Pump Metering Platform, it adopts High-temperature Catalytic Combustion Oxidation Method, combined with gas purification device and Non-Dispersive Infrared CO2 Absorption Technology to convert organics in the sample into CO2 for measurement. It realizes automatic TOC online monitoring of high accuracy, low detection limit, high stability and less maintenance.
