How to Use Your SwimSense Test Kit

Follow the steps below to obtain the most accurate results.

Using the 16-in-1 Water Quality Test Strip (Long Strip)

Step 1 - Collect Your Water Sample

Collect a small sample of water in a clean container, or carefully take a sample directly from the water body you wish to test. Avoid disturbing sediment or debris where possible.

Step 2 - Remove the Test Strip

Remove one long 16-in-1 test strip from the tube and immediately replace the lid to protect the remaining strips from moisture.

Step 3 – Dip the Strip

Dip the coloured test pads on the strip fully into your collected water sample for 2 seconds, then remove and shake off excess water droplets

Step 4 – Wait for the Colours to Develop & Compare with the enclosed colour chart

Hold the strip flat (horizontally) for 30 seconds while the test pads react with the water sample. After 30 seconds, compare each test pad to the corresponding colour scale on the chart provided. Continue checking the colours over the next 30 seconds for the most accurate reading.

Using the Ammonia Nitrogen Test Strip (Short Strip)

Step 1 – Remove the Test Strip

Remove one ammonia nitrogen test strip from the silver foil packet in tube and replace the lid securely.

Step 2 – Dip the Strip

Dip the test pad fully into your collected water sample for 5 seconds.

Step 3 – Remove the Strip

Remove the strip from the water, lay horizontally (flat) and allow the test pad to develop naturally.

Step 4 – Wait for the Result

Place the strip on a flat surface and wait 3 minutes for the colour to fully develop. After 3 minutes compare the colour of the test pad to the Ammonia Nitrogen chart provided to determine your result.

Tips for Best Results

  • Test away from obvious debris, mud or floating material.
  • Read results in natural daylight wherever possible.
  • Avoid touching the coloured test pads with your fingers.
  • Keep unused test strips dry and store them in a cool, dry place.
  • For larger rivers, lakes or beaches, consider testing more than one location.
  • Take a photograph of your results next to the colour chart for future reference.

Your Water Quality Guide

SwimSense helps provide an indication of water conditions that may be associated with pollution, runoff and changes in water quality.

Changes in certain readings can sometimes indicate factors that swimmers may wish to be aware of, including:

  • Agricultural runoff from nearby farmland
  • Urban runoff from roads and built-up areas
  • Storm overflow impacts following heavy rainfall
  • Elevated nutrient levels that may contribute to algae growth
  • Industrial contamination or historic pollutants
  • Changes in water chemistry that could affect comfort while swimming

SwimSense is designed to help you better understand the water you are entering and identify conditions that may warrant additional caution or further investigation.

Understanding Your Results

SwimSense can help identify conditions that may be associated with pollution, runoff, nutrient enrichment and changes in water quality.

Higher readings may indicate:

  • Agricultural runoff
  • Urban runoff
  • Storm overflow impacts
  • Industrial contamination
  • Elevated nutrient levels
  • Reduced water quality

Results should always be considered alongside local knowledge, visible water conditions and official guidance.

Important Information

SwimSense is a screening tool designed to provide indicative results only.

SwimSense does not directly test for E. coli, enterococci, viruses or all contaminants and should not be used as a replacement for laboratory testing.

Always follow local safety advice, official warnings and signage before entering any body of water.
