In Europe, authorities have determined that parts per million (ppm) sensors offer optimal disinfection protection for swimmers. This has led to an increase in the use of ppm sensors to control chlorine levels in pools over the past 20 years. In the United States and other parts of the world, ORP measurement is still the primary method for pool control, but the trend is slowly transitioning towards using ppm sensors. This is because more and more pools are realizing that they can achieve better control with ppm sensors, resulting in better treated water, less corrosion, lower chloramines (chlorine smell), and reduced chemical costs.

The control of both pH and chlorine dose is done in an extremely powerful, yet simple. PID control  loop with plenty of protection such as overfeed protection, as well as secondary set point dosing to manage faecal incidents.
