Lovibond, 515731BT, DPD No.3 High Calcium, Tablet Reagent in Blister, Middle Pack
Features:
DPD No.3 is used in the DPD method for the determination of chlorine and for the correct dosing of the water care product. DPD No.3 High Calcium is used to determine the level of total chlorine, especially for water that has a high calcium hardness. The DPD No.3 tablet is added to the water sample after the free chlorine has already been determined with DPD No. 1. The tablet is crushed with the stirring rod and mixed by swirling. Now the value can be measured. If the value of free chlorine is subtracted from this value, the content of combined chlorine is present. DPD No. 3 can also be used to determine bromine, ozone and monochloramine-dichloramine.
