HydroHawk Legionella Swab Test for Water Outlets - Single-Use Legionella Testing Kit for Legionella pneumophila SG1. Water Testing Kits for Pools, Air Con Units, Hot Tubs, Shower Heads, Taps & Hoses

HydroHawk Legionella Swab Test for Water Outlets - Single-Use Legionella Testing Kit for Legionella pneumophila SG1. Water Testing Kits for Pools, Air Con Units, Hot Tubs, Shower Heads, Taps & Hoses

HydroHawk
Why we love it
  • Quick results in 25 minutes.
  • Complete kit for easy testing.
  • Sensitive detection of harmful bacteria.
Main Highlights
  • LEGIONELLA WATER TESTING KIT - The HydroHawk single-use swab water test kit includes everything required to carry out one full test, including a sterile swab, pre-filled buffer vial, test strip, and step-by-step pictorial instructions. No extra tools or lab skills needed, making it ideal for home, work, or travel.
  • HIGH SENSITIVITY - Designed to detect Legionella pneumophila SG1 at 200 CFU or higher per swabbed area, the HydroHawk water outlet & pool test kit alerts you to even early-stage contamination, helping reduce risk before infection can occur (especially in high-use or warm water systems). The slimy buildup that forms in shower heads, taps, hoses and pipes (called Biofilm) is often where Legionella bacteria hides, and HydroHawk is designed specifically to test this surface residue and alert you to dangerous growth zones with high levels of sensitivity.
  • QUICK & EASY - HydroHawk water outlet & pool tester swabs deliver results in just 25 minutes and can be easily used without the need to send samples away to a lab. Ideal for landlords, homeowners or travellers looking for a quick and reliable water contamination test kit. The included recovery buffer vial is pre-filled and ready to go, allowing you to simply swab the surface and mix with the buffer to extract any Legionella pneumophila.
  • WHY LEGIONELLA TESTING MATTERS – Legionella bacteria can thrive in man-made water systems like taps, showers, and hot tubs. When inhaled through mist or steam, Legionella pneumophila SG1 can cause serious illness including Legionnaires’ disease – a potentially fatal pneumonia with long-term effects. Regular swab testing is a key part of prevention, especially in high-risk environments.
  • HYDROHAWK – Backed by nearly 20 years of testing expertise and used by professionals in over 75 countries, our pool and hot tub tester products have been rigorously tested by Hydrosense’s in-house scientists - the same team trusted by hospitals, hotels, and global businesses to protect public health. Trust HydroHawk for clear, professional accuracy and peace of mind every time you use your pool, spa or hot tub.
