## Description

Lovibond DPD No.1, DPD No.3 & pH Tablets Pack Phenol Red is used for pH measurement. The tablet produces characteristic colour changes when dissolved in the water sample. The pH value is important for the disinfection effect of water care products. It can also cause corrosion or precipitation and thus damage materials. This tablet has been developed for use in photometers. DPD No. 1 tablets are used to determine the free chlorine: The tablet is placed in a cuvette with a few drops of the water sample and crushed, sample water is added and mixed by swirling. The value can be measured immediately. DPD No.1 is also used for the determination of bromine, ozone and monochloramine-dichloramine. DPD No.3 is used to determine the level of total chlorine. 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. With DPD No. 3, bromine, ozone and monochloramine-dichloramine can also be determined.
