Avoid Unseen Risks Before You Swim
SwimSense gives you peace of mind in just minutes. Developed with our in-house chemist, these dual-strip test kits check for 16+ key water safety parameters — including pollutants, heavy metals, pH, and Ammonia Nitrogen — all in under 3 minutes.
Perfect for wild swimmers, cold water dippers, families, SUPers, and outdoor adventurers.
What It Tests For
- Long Strip (15 Parameters): pH, Total Alkalinity, Carbonate, Hardness, Cyanuric Acid, Copper, Mercury, Total Chlorine, Free Chlorine, Bromine, Nitrate, Nitrite, Iron, Chromium VI, Lead, Fluoride
- Short Strip: Ammonia Nitrogen (wait 3 minutes)
Each pad is colour-coded with a safety key:
- 🟩 Green = Safe to swim
- 🟨 Yellow = Caution or extra vigilance
- 🔴 Red = Unsafe to swim

How It Works
- Dip your long test strip in the water for 2 seconds, then remove and carefully shake off any excess water.
- Hold the strip horizontally for 30 seconds then compare the pads to the colour chart.
- Dip the second short strip (labelled Ammonia) for 5 seconds, then remove and carefully shake off any excess water.
- After 3 minutes, compare the pads to the Ammonia Nitrogen Chart.
