Product Details

Dual channel alkalinity analyzer
The alkalinity of water is an important indicator of water quality and has a significant impact on industrial water use.
Alkalinity refers to the absorption in waterprotonThe ability is usually calibrated based on the total amount of substances in water that can react quantitatively with strong acids. The formation of alkalinity in water is mainly due to heavy carbonates, carbonates, andhydroxideThe presence of borates, phosphates, and silicates can also produce some alkalinity. Wastewater and other complex water systems also containorganic-baseClass, metal hydrolysissaltAll of them are components of alkalinity.
In these cases, alkalinity becomes a comprehensive indicator of water, representing its ability to withstand strong acids滴定The total sum of matter.
To provide a basis for determining water quality and conducting water treatment.To meet the needs of on-site online analysis, traditional and mature national standard testing methods are adopted, which have the advantages of miniaturization, integration, and automation.
