HK-8010A Chemical Oxygen Demand (CODcr) Online Monitor
HK-8010A Chemical Oxygen Demand (CODcr) Online Monitor
Product details
Chemical Oxygen Demand（COD）It refers to the corresponding mass concentration of oxidant consumed when using strong oxidants to oxidize organic and inorganic reducing substances in water samples under certain conditions.CODIt reflects the degree of pollution of water bodies by organic and inorganic reducing substances.
The instrument adopts automatic control of water sample collection, digestion and oxidation, reaction measurement, data processing and transmission, and quickly and continuously completes the automatic process of wastewater treatmentCODThe entire process of analysis.
The instrument is designed according to the oxidation principle of potassium dichromate method. In the experiment, a known amount of potassium dichromate solution is added, and in a strong sulfuric acid medium, silver sulfate is used as a catalyst. After high-temperature digestion, the chemical oxygen demand is determined by spectrophotometry（COD）Value.
◆The 7-inch LCD touch screen is easy to operate, with a beautiful and elegant interface, and rich and intuitive display content.
◆The integrated design of digestion and measurement ensures more accurate and rapid measurement results.
◆The light source adopts imported monochromatic photodiodes, which have excellent performance, energy concentration, and low power consumption.
◆Adopting high-precision injection pump, with high measurement accuracy and low reagent consumption.
◆Adopting acid alkali and high temperature resistant valve circuits, with long service life and minimal manual maintenance.
◆The instrument is equipped with a preprocessing device inside, which can meet the requirements of different water quality measurements.
◆It has an automatic calibration function to ensure that the instrument can measure more accurately.
◆Equipped with intelligent maintenance function, it automatically cleans after each inspection to ensure more accurate measurements and reduce manual maintenance.
