COD – Chemical Oxygen Demand

Online Reagent Free COD Analyzer for handling High Salts, Fatty and High Particles Sample

LAR QuickCODultra Analyser is the most reliable measurement system for the roughest waste water applications. Due to high temperature combustion at 1200 deg C, this model is excellent in handling sample content, high salt, fatty and high particle samples.

Almost all type of sample can be measured accurately by this unit.

The high combustion method goes without any use of dangerous and etching substances so that a high operational safety is ensured.

The measurement results are taken from the complete digestion which is free from chloride interference.
