The GM Series is a fully controlled salt water management system. A multi-electrode probe analyses water chemistry and determines how much chlorine needs to be produced by the electrolytic cell. The probe also assesses the pH of the water and adjusts as necessary. The GM Series has been specially designed to automatically manage mineral pools. The water chemistry of mineral pools is surprisingly complex, but a GM Series system takes the guesswork out of managing your pool.

The GM Series Gemini measures your pool water’s ORP and pH levels accurately so it can automatically activate the chlorinator when required to sanitise your pool whilst also dosing liquids to balance pH levels.
