KWS-850 on-line multi-parameter water quality sensor for water treatment quality monitoring
Product Description
The KWS-850 on-line multi-parameter water quality sensor is an essential device for water treatment quality monitoring. It can simultaneously measure multiple crucial parameters, providing comprehensive data to ensure the effectiveness and safety of water treatment processes.
Firstly, it measures pH value, which is vital for understanding the acidity or alkalinity of water. Maintaining the appropriate pH range is crucial for the efficiency of chemical processes in water treatment and for preventing corrosion or scaling in pipes and equipment.
Secondly, the sensor monitors dissolved oxygen levels. Sufficient dissolved oxygen is necessary for the survival of beneficial microorganisms in biological treatment processes and for ensuring the quality of the treated water.
The KWS-850 also measures conductivity, which reflects the total amount of dissolved ions in the water. This parameter helps in assessing the effectiveness of processes like filtration and reverse osmosis in removing impurities.
Turbidity measurement by this sensor is another important feature. It indicates the presence of suspended particles in the water, and keeping turbidity low is essential for producing clear and safe water.
In addition, parameters such as temperature, total dissolved solids (TDS), and specific ions like ammonia nitrogen and nitrate can also be measured by the KWS-850. Temperature affects the rate of chemical reactions and biological activities in water treatment, while TDS provides an overall indication of the dissolved substances in the water. Monitoring specific ions helps in detecting and controlling potential contaminants and ensuring compliance with water quality standards.
