See More Than Today's Reading.
A single chemistry reading tells you what's happening now. PSI helps operators understand the operating history around that reading.
PSI combines connected controller data, chemical-feed activity, trends and verified field testing to provide a more complete picture of changing water conditions.
- pH Monitoring — track current conditions and historical trends.
- ORP Monitoring — view ORP alongside chemical-feed activity.
- Chemical Feed History — see when chemicals were fed, how long dosing occurred and what happened afterward.
- Verified Field Testing — bring technician test results into the same operational view as connected pool data.

Another Layer of Visibility Between Physical Tests.
PSI uses pool operating data, chemical-feed activity and verified testing to estimate free chlorine between physical tests. Projected FAC provides another point of reference for understanding changing water conditions while maintaining the importance of required physical testing.
More context. Better visibility. Better-informed decisions.
Each projection is locked in before a technician's physical test result is entered, then graded against it. The confidence shown with every projection reflects the pool's own test history. Projected FAC is an estimate: it never replaces required physical testing and does not control chemical feed.
