This instrument performs analysis of COD ( Chemical Oxygen Demand) in river water or plant effluent. The analysis is based on the " Acid Potassium Permanganate Method" ( conforms to JIS K0102) . In cases where the sample contains a high level of chlorine ions ( such as sea water) , an alternative alkali measurement method is employed. Features: - High reliability : proven oxidation - reduction potentiometric method is adopted - Reducing routine maintenance work : Adoption of pinch valves and larger tube, and cleaning system of the sample line for every measurement, reduces clogging - Titration curves indication and print-out is available - Used-friendly interactive operation using touch-screen - Sufficient data storage capability : internal memory for 14 day measurement data and data retrieval function - Oxalic acid cleaning system cleans up the reactor vessel and electrode contaminated with over-provided permanganate - Ammonia cleaning is available as option to remove contamination with precipitated silver chloride.
