Water quality COD rapid analyzer

The water quality COD rapid analyzer employs the principles of chemical digestion and photometric detection. It decomposes organic matter in water samples using strong oxidizing agents under high temperatures and calculates COD concentration by measuring the absorbance of the reaction solution at specific wavelengths. It is used for on-site rapid monitoring of organic pollutant levels in sewage and industrial wastewater, with an operation time of approximately 15 minutes.
Selection
When selecting, focus on ensuring that the measurement range covers the concentration of daily testing samples, maintain the digestion temperature at 165℃ ± 2℃ to ensure oxidation efficiency, and ensure the instrument has anti-chloride ion interference capabilities. Verify whether the instrument is equipped with pre-made reagents and if its protection level meets the requirements of the on-site environment. Compare the detection accuracy and operational complexity of different models.
