Palintest Calcium Hardness Photometer Tablets 1 & 2 Test Tablets
Calcium hardness is caused by the presence of calcium ions in the water. Calcium salts can be readily precipitated from water and high levels of calcium hardness tend to promote scale formation in water systems.
Calcium hardness is an important control test in industrial water systems such as boilers and steam raising plant; and for swimming pool waters.
The Palintest Calcicol test provides a simple method of determining calcium hardness over the range 0 - 500 mg/l CaCO3.
Method
The Palintest Calcium Hardness test is based on the Calcicol indicator reagent method. Calcium ions react specifically with Calcicol indicator in alkaline solution to give an orange coloration. The reagent itself gives a violet colour in solution. Thus at different calcium levels a distinctive range of colours from violet to orange is produced.
The reagents for the method are provided in the form of two tablets. The test is carried out simply by adding one of each tablet to a sample of the water.
The colour produced is indicative of the calcium hardness and is measured using a Palintest Photometer.
