A critical element of disinfection is accurate dosing and monitoring of the ClO2 level in the water. Adding chlorine dioxide in the right concentration saves material, protects the environment and the health of the end user of your product. Continuously monitor the chlorine dioxide level in the water with the Hach Lange 9187 sc analyzer.
High range hardness reagent kit, 100 - 4000 mg/L as CaCO3
The first titration gives results for the calcium hardness and the second titration gives the total hardness. The difference between the values is the level of magnesium hardness. All concentration results are given in mg/L CaCO3.
