The Taylor Calcium Indicator Liquid (3/4 oz / 22 mL) is a colorimetric reagent used in Taylor Water Technologies test kits to measure the calcium hardness of pool and spa water.
This indicator liquid is used in combination with Calcium Buffer (R-0010) and Hardness Reagent (R-0012) to perform a precise titration. It allows for the visualization of the color change that indicates the end of the chemical reaction, thereby ensuring an accurate reading of results.
Regular monitoring of calcium hardness is essential to prevent corrosion (if the water is too soft) or scaling (if the water is too hard), ensuring the longevity of your equipment and the comfort of swimmers.
