COD online water quality analyzer (chromium method)
Chemical oxygen demand (COD) is a chemical method to measure the amount of reducing substances that need to be oxidized in water samples. Oxygen equivalent of substances that can be oxidized by strong oxidant in wastewater, effluent from wastewater treatment plant and polluted water. Wtf2000-codcr COD on-line water quality analyzer adopts the national standard fast digestion spectrophotometry for analysis, the detection range standard is 0-1000mg / L, and the range can be expanded according to the actual water sample on site (the chloride ion concentration shall not be higher than 1000mg / L). In the strong acid medium, silver sulfate was used as catalyst, after rapid digestion at high temperature and high pressure, the reagent was added for spectrophotometric measurement.
Product overview

Chemical oxygen demand (COD) is a chemical method to measure the amount of reducing substances that need to be oxidized in water samples. Oxygen equivalent of substances that can be oxidized by strong oxidant in wastewater, effluent from wastewater treatment plant and polluted water.

Wtf2000-codcr COD on-line water quality analyzer adopts the national standard fast digestion spectrophotometry for analysis, the detection range standard is 0-1000mg / L, and the range can be expanded according to the actual water sample on site (the chloride ion concentration shall not be higher than 1000mg / L). In the strong acid medium, silver sulfate was used as catalyst, after rapid digestion at high temperature and high pressure, the reagent was added for spectrophotometric measurement.
