AstralPool RolaChem RC9 GPO/GPO ORP & pH Controller for Automatic Monitoring and Dosing with Dual GPO Outputs

Where external chemical dosing equipment is already installed, accurate monitoring and control become the key factors in maintaining stable pool water conditions. The AstralPool RolaChem RC9 GPO/GPO provides automatic management of sanitiser and pH levels through a dedicated controller platform, helping reduce manual intervention while supporting healthier and more comfortable swimming water.

Unlike models incorporating integrated dosing pumps, this configuration uses GPO outputs for both sanitiser and acid control. This arrangement allows the controller to monitor water chemistry and manage connected dosing equipment according to measured requirements. Controlling sanitiser and pH together helps maintain effective water treatment while supporting lower sanitiser consumption and more balanced water conditions.

Accurate measurement is provided through sanitiser and pH sensors featuring inbuilt amplifiers. These sensors continuously monitor water conditions and transmit information to the controller, allowing it to determine when corrective action is required. Automatic monitoring and dosing control help maintain target water chemistry levels without the continual cycle of manual testing and adjustment.

Consistent water balance contributes to swimmer comfort and overall pool health. By reducing fluctuations in sanitiser activity and pH levels, the RC9 helps minimise red eyes and skin irritation while reducing maintenance requirements associated with manual chemical management. The result is a more efficient and controlled approach to pool water treatment.
