Product Overview

COD is an important indicator to reflect the extent of water pollution ,which is polluted by the organism and inorganic reducing substances.

COD means under certain conditions, mass concentration of oxygen consumption, when use strong oxidizer, make organism and inorganic reducing substances oxidation. This analyzer can automatic continuous work for long-term in an unattended manner. And it is widely used in industrial pollution discharge wastewater, industrial process wastewater, industrial wastewater treatment plants, municipal wastewater treatment plants and so on. Depending on the complexity at the scene, for ensure reliable and accurate testing, can choose different pre-treatment system.


Product Principle

Add the quantitative potassium dichromate solution to the sample; in the strong acid medium, use the silver sulfate as catalyst and make use of the unique dilution injection technology to reduce the concentration of chloride ion and the combined masking agent to mask the high concentration of chloride ion. After digestion at high temperature and pressure, determine the concentration of COD with spectrophotometry.


Product Characteristics

Adopt the new photoelectric quantitative technology, which is not affected by the high chroma, many suspended solids, lots of bubbles and other interference factors, thus ensuring high reliability and precision as well as strong anti-interference ability;

Be characterized by high detection accuracy, low lower limit of measurement and small long-term drift amount of instrument;

Be featured with functions of self-test with one key and self-diagnosis;

Adopt the single-channel high-integration valve set, which ensures simple and quick maintenance and cleaning;

Be configured with 24-hour networking function, thus monitoring the running state of instruments at anytime and anywhere;

Be featured with functions of alarm, quality control and reverse control;

Be characterized by functions of automatic cleaning and automatic calibration;

Be featured with functions of hourly measurement, interval measurement and externally controlled measurement;

Be able to work automatically after power down and recovery;

Be featured with automatic prompt and automatic reset in case of fault and lack of reagent (sample);

Have the function of fault recording;

Can save more than 3 years of historical data;

Meet the requirement for the separate discharge of cleaning liquid and waste liquid.
