Water hardness is one of the most popular analyses when it comes to water quality determination, being important for both human health and industrial productivity. Until now, various national and international norms described the analysis of water hardness by manual titration with visual endpoint determination. This subjective technique is prone to human errors and can lead to less accurate and reproducible results. The new norm ASTM D8192 presents how water hardness (total, calcium, and magnesium hardness) can be determined by photometric titration with an optical sensor for objective endpoint determination.
