Frequently Asked Questions
What makes a true free chlorine sensor different from ORP-based measurement?
ORP measures the oxidizing power of the water in millivolts — a high ORP indicates strong sanitizing capacity, but the actual chlorine PPM is inferred rather than measured directly. A true free chlorine sensor measures the actual concentration of free chlorine (hypochlorous acid) in the water directly, independent of pH or cyanuric acid levels that can distort ORP readings. This gives operators a more accurate, trustworthy chlorine reading particularly in pools with stabilizer.
What is solid-state sensing technology?
Solid-state sensors have no moving parts or liquid-filled reference junctions that can wear, clog, or drift over time. This translates to higher reliability, less frequent calibration, and lower maintenance costs compared to traditional glass electrode or conventional electrochemical sensors.
Does the cellular connectivity require a subscription?
Cellular connectivity may require a data plan or subscription — confirm current terms directly with Hayward. WiFi access to the remote monitoring platform is typically included at no additional cost.
How does the CAT 6000 compare to the CAT 5000 and CAT 5500?
The CAT 6000 represents a generational leap with true free chlorine measurement (rather than ORP), solid-state sensing technology, a full-color touchscreen, energy consumption monitoring, and integrated WiFi plus cellular. The CAT 5000 uses satellite/cellular/WiFi with pH and ORP; the CAT 5500 adds salt/TDS monitoring for salt chlorine pools. The CAT 6000 is the most accurate and lowest-maintenance of the lineup.
