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
Use injection pump and ten-way rotary valve to extract sample quantificationally; high accuracy and less cross contamination between the reagents.
Adopt new NDIR CO2 detection technology, realizing high stability.
Multiple modes: TC, IC, TOC, NPOC can be measured in the same reactor, switching as required.
Direct switching between TOC and COD can be achieved simultaneously, realizing online measurement of COD in the sample.
Multi-channel valve terminal of high integration, with simple and fast maintenance, disassembly, assembly and cleaning.
Built-in check module, equipped with zero check and span check.
Store data of ten years; support 2 different ways of protocols for uploading at the same time.
Less space occupying, modular design of high integration, easy for maintenance and can be used for integration with water station system.
Applied to TOC online monitoring in industrial wastewater, centralized drinking water and surface water.
