Macherey Nagel 91324 QUANTOFIX Carbonate hardness

Macherey Nagel 91324 QUANTOFIX Carbonate hardness

The Macherey Nagel 91324 QUANTOFIX Carbonate hardness designed for rapid determination of calcium (Ca²⁺) concentration in water samples. Therefore, they are highly suitable for on-site testing and routine analysis in laboratories, industrial settings, and environmental monitoring. Moreover, these strips utilize the Glyoxal-bis(2-hydroxyaniline) method, ensuring reliable and consistent detection of calcium ions.

In addition, the strips provide a clear color change from yellow to red, allowing easy visual interpretation. As a result, users can quickly estimate calcium levels using the provided color scale. Furthermore, the inclusion of additional reagents enhances measurement accuracy, especially for semi-quantitative analysis.

Key Features
