Everything about E.W.A.
Continuous pH monitoring
E.W.A. samples your water every 10 minutes and alerts you the moment pH drifts outside the optimal 7.2–7.6 range — before it becomes a problem.
ORP-based sanitizer verification
Chlorine dose tells you what you added. ORP tells you if it is actually working. E.W.A. measures both so your water is always genuinely safe.
Precise dosing advice
When correction is needed, E.W.A. tells you exactly how much chemical to add. No guesswork, no over-dosing, no wasted product.
No test strips required
144 readings per day, automatically. You will never dip a test strip or wonder if the colour reading was accurate again.
Smart push alerts
Notifications arrive the moment a parameter drifts. Fix issues in minutes, not hours. Water quality never catches you off guard.
