The Chemistry Probe Kit (ATT-CPK) ensures the accurate readings of pH balance and sanitizer levels, and when combined with The Attendant’s ability to operate any manufacturer’s equipment, helps in keeping your pool pristine all season long! Our probes have gone through a rigorous NSF 50 testing process to ensure consistent, reliable measurements of your pools water quality. When coupled with The Attendant + Chemistry, the system will automatically determine how much filtration is necessary and time the work in the most energy efficient way. From there, The Attendant + Chemistry will monitor the amount of sanitizer and pH in your pool and dispense chemicals to address any imbalances. No one wants algae in their pool. The Attendant + Chemistry can react to algae or extra heavy pool use by automatically boosting sanitizer and filtration run times.
