Water Quality Digester

The water quality digester decomposes organic matter in water samples into inorganic ions through heating and the addition of chemical reagents. It is used to measure indicators such as chemical oxygen demand (COD), total phosphorus, and total nitrogen in water, serving as a routine pretreatment device in the fields of environmental monitoring and water treatment.
Selection
When selecting, consider heating uniformity and temperature control accuracy, and match the sample capacity with detection requirements. Pay attention to the corrosion resistance of materials, and confirm the availability of supporting reagents. Check the safety protection design and verify the equipment's compliance with current testing standards.
