CHCM-210- Total Hardness Meter

CHCM-210

[Product Overview]

Total hardness refers to the combined concentration of calcium, magnesium, and other metal ions in water, serving as a crucial indicator of water quality. The total hardness meter employs specific reagents that react with calcium and magnesium ions to form colored compounds. These compounds are then quantified by measuring their absorbance using a photometer. This method allows for the determination of total hardness in various types of water, including natural water bodies, drinking water, industrial water, and wastewater, ensuring compliance with relevant standards.

[Application Area]

Widely used in drinking water, groundwater, surface water, municipal sewage, industrial sewage, environmental monitoring, colleges and universities, scientific research institutions and other fields water measurements.
