Notes:
DPD 1 A and DPD 1 B reagent MUST be added to the vial BEFORE water sample is added to
avoid misreadings!
Turbidity caused by high concentration of calcium ions will affect the measurement result. To
prevent that, please use DPD HC (High Calcium) reagents.
Do not clean glassware and equipment with household detergents, as these could greatly
reduce the measurement result. To prevent any contamination, the cuvette, lid and stirrer
should be stored in a 0.1 % sodium hypochlorite solution for one hour. Then rinse with distilled
water, thoroughly.
