Municipal swimming Pools and Spas use chlorine as a disinfectant and so use a pool controller to control the amount of chlorine that gets dosed. The AquaSense Swimming Pool Controller and Spa Controller measure the pool chlorine levels and the pH of the pool and then control the chlorine and pH levels by controlling the chemical dosing. The AquaSense advanced pool controllers offer bufferless and reagentless operation.
treaming Current Monitors and Streaming Current Detectors from Pi use streaming current measurement (similar to Zeta Potential) to maintain proper electrokinetic charge (ionic & colloidal) in coagulation control applications in water treatment. Effectively these coagulation analyzers detect and control the level of residual coagulant.
