Calcium is often present in water supplies due to the water passing over deposits such as limestone. Calcium is essential for plant and animal nutrition as it is a fundamental constituent of bones, shells and plant structures, so calcium levels must be monitored in aquaculture. Calcium carbonates in water can result in water hardness which may lead to pipe scaling, so it is important to monitor calcium levels in boilers and cooling towers.


Hanna offer a wide range of Photometers and ISE instrumentation that are suitable for accurate measurements of calcium levels.
