HI 3825 Combination Swimming Pool Test Kit

Swimming pool water requires daily tests for alkalinity, bromine, chlorine and pH.
Chlorine and bromine, which kill microorganisms, are commonly used in swimming pool water because of their disinfectant properties.
Alkalinity and pH should be monitored because their concentration in pool water affects the proper activity of the disinfecting agents.
Bromine and chlorine tests are colorimetric (color comparison), while alkalinity tests are a titration.

pH tests are performed with HANNA‘s pHep® pH tester. The pHep® offers greater accuracy and a wider range than litmus paper.
