HANNA HI 3825 COMBINATION SWIMMING  POOL & SPA TEST KIT

Swimming pool water requires daily tests for alkalinity, bromine, chlorine and pH.

Chlorine and bromine, which kill micro-organisms, are commonly used in swimming pool water because of their disinfectant properties.

Alkalinity and pH are monitored because their concentration in pool water affects the proper activity of the disinfecting agents.

Bromine and chlorine tests are colorimetric (color comparison), alkalinity is a titration and pH tests are performed with HANNA® ' pH pocket tester, pHep, that guarantees greater accuracy than litmus papers and over a wider range.
