K-1705 Hardness Titrets Kit is used to determine Hardness levels from 50-500 ppm

Hardness Information

$33.00

The K-1705 Hardness Kit was designed to accurately measure the levels of water hardness from 50-500 ppm. K-1705 uses the EGTA Method. The EGTA method is specific for calcium hardness. The EGTA titrant in alkaline solution is employed with a zincon indicator. Results are expressed as ppm (mg/L) CaCO3. 

Hardness is a measure of the mineral content of water. Calcium and magnesium are the most common minerals that contribute to hardness. Hard water causes scaling in boilers and other industrial equipment, and diminishes the effectiveness of soaps and detergents.
