COD Analyzer

Measurement method Acid potassium permanganate method Alkaline potassium permanganate method Potassium bichrornate method Justice for pollution test method 1. Operation A special feature of this instrument is the conversation-typed touch screen or users' ease of operation. All programs are structured for user-friendly handling and can be operated easily with simple manipulation by all users Reaction time control makes measurement meet the field conditions By realtime analysis. Oquick handling for environment change is possible Instrument status, COD concentration, Flow rate, and calculation result of load weight is output hourly and daily. 2. Stability As it performs pre-measurement everytime to decide optimum sampling volume, accurate measurement less affected by load change of COD concentration is possible Since KMnO4 pump decides rotational frequency and controls the fixed quantity by photoelectric detector, it has a high level of titration COD measurement of dilution water, blank valve with refill of reagent(zero correction), and factor calibration of KMnO4 is automatically controlled by computer, there is no influence by reagent change. Stable measurement is possible even with polluted sample by oxidation and reduction measurement Environment friendly analysis is possible by using silver nitrate which eliminate CL-ION influence(option) Dilution device attached, suits COD with high concentration(option) 3. Counterplot When malfunction or poor performance occurs, error message and LED are printed out, alarm signal waorks, and proper handling is possible. Able to convert to alkaline KMnO4 method by simple internal operation Inputs regulated value of COD concentration, easy COD control. When using CEMS, able to receive the result from the field and long distance
