Our most comprehensive range, detecting all Legionella pneumophila serogroups (sg) 1-15. The three-line test distinctly identifies sg 1 on one test line and sg 2-15 on another.

Extremely sensitive, this test is available for water or biofilm testing, detecting bacteria levels as low as 100 CFU/L (0.1 CFU/ml) in water and 200 CFU per swabbed area. Action levels are provided at 1,000 CFU/L (1 CFU/ml) and 10,000 CFU/L (10 CFU/ml).

HYDROSENSE ONE RANGE

This range focuses on detecting Legionella pneumophila serogroup (sg) 1, the cause of over 90% of Legionnaires’ disease outbreaks2. This range offers test kits for water only.

The most sensitive test in this range (Ultra) detects bacteria levels at >100 CFU/L (0.1 CFU/ml). In the Hydrosense ONE range there is also the option of (Multi) test kits, which have a sensitivity level of 1000 CFU/L, with an action level at 10,000 CFU/L.

Legionella pneumophila, is a dangerous waterborne bacterium, which can lead to fatal respiratory diseases in humans, such as Legionnaires’ disease or cause a milder illness called Pontiac fever.

What are the risks in my industry?

Legionella is a waterborne bacterium that lives universally in the natural environment. It only becomes an increased risk to human health when it enters the built environment.

As such, any sector that has a water system that can be accessed by humans, could be at risk of Legionella contamination.
