The RP9 pH Controller incorporates a sophisticated sensor and inbuilt peristaltic pump to dose acid into pools and spas and accurately control pH balance. The sensor incorporates an inbuilt amplifier at the sensing point which minimises interference from other power cables or EMC and is optically coupled with the micro processor in the control unit to provide isolation from power spikes or earth leakages that otherwise can affect the processors’ performance.
The Controller is easy to operate, provides a power outlet to control the pool filtration pump and a large LCD display for all operating functions. The software uses fuzzy logic to “learn” the dosing requirements over a period of time making the pH set point more accurate to achieve and help minimise over dosing. Available with a range of peristaltic pumps sizes from 1 to 100rpm.
