Eff ects of the stabiliser on the chlorine and the ORP
A pool has a stabiliser content of 30 ppm and a pH of 7.4.
1 ppm free chlorine = 700 mV
Therefore, the user can set their chlorinati on requirement to 700 mV to maintain a level of 1 ppm in the pool.
If the level of stabiliser increases to 90 ppm, the ORP reading will be false.
1 ppm free chlorine = 500 mV
If the user keeps his setpoint at 700 mV, he will end up chlorinati ng up to 5 ppm !
