LAR COD Analyzer : QuickCOD ultra

The raw water sample is oxidized at 1,200 °C and the CO2 produced is deteced and quantitatively determined. High Temperature Method at 1,200 °C

LAR’s COD analyzer QuickCODultra™ is the most reliable measurement system for the roughest wastewater applications. Due to an unrivaled injection and oxidation technique, the QuickCODultra easily handles sticky, fatty, salty, and high-particle samples unlike other COD analyzers without the need of any hazardous chemicals.
