Direct Test Kit

The Legionella Direct Test Kit is the fastest and the simplest test in the Hydrosense Product Range as it has no filtration step. It provides a sensitivity of 100,000CFU/L. It requires no sample preparation and can be used to test the water collected from any source. Because of the lower sensitivity, this kit is not recommended for applications where an action point below 100,000 CFU/L is required.

Why use the Hydrosense Test?

  • It provides an immediate picture of Legionella contamination risk, which allows you to make quicker, better-informed decisions about improving water quality.
  • The rapid test helps you to maintain high service standards and protects you from reputational damage.
  • The test helps to reduce public and employee health risk by minimising the time taken to identify Legionella.
  • Recording test information while analysing data helps to create a complete picture of Legionella contamination risk and a roadmap to prevent future outbreaks.
  • This responsible approach is not only the right thing to do, but it is also smart for your organisation. Long lawsuits, huge fines and reputational damage following an outbreak can quickly destroy your business.
