Accurate swab testing to detect Legionella on surfaces

Biofilm is very common and can be found inside pipework, taps, shower heads and water tanks and is often overlooked when it comes to Legionella risk. A majority of Legionella, if present, could be locked in biofilm.


This Hydrosense Legionella Swab Test is an easy option for quickly sampling surface biofilms. Instead of testing a water source you simply swab the area to obtain the biofilm sample. Legionella grows in biofilms, therefore testing the surface of shower heads, air conditioning units, water tanks, taps, spa pools etc. while paying particular attention to any biofilm deposits, gives a very accurate picture of the condition of your water system. This kit is also very useful for locating the source of infection, which often will be within biofilms.

  • Very sensitive & easy to use test
  • Kit includes everything required to carry out the test

  • Audit trail: log & report the results using the Hydrosense App

The Hydrosense legionella pneumophila Sg-1 test has been shown to produce weak positive results with other legionella pneumophila serogroups at the cfu/ml stated in the above list.


  • A wide range of non-oxidising biocides and bio dispersants have been checked for cross reaction and interference with the test.
  • The test should not be used on systems treated with biguanide or tetrakis hydroxymethyl phosphonium sulfate (THPS) based biocides.

The Hydrosense Legionella Tests are an easy-to-use, on-site test solution for water and biofilms, that detect Legionella pneumophila sg1 antigen (see One Ultra Range) or sg1-15 (see Pro Ultra Range). All it takes is approx. 10 minutes to conduct the test process and 25 minutes wait for the results.

Hydrosense Legionella

Hydrosense Legionella Water Test Kits offer very sensitive detection limits of 100 CFU/L for the water test and 200 CFU per swabbed area for the swab test. A perfect choice for high-risk industries or in countries where there are stricter Legionella action levels.

Hydrosense ONE Ultra Legionella Water Test: This test can be used on water samples from any source to detect Legionella pneumophila serogroup 1 (LpSG1). The unique Hydrosense filter, included in the kit, captures any Legionella present in the sample as the water is pushed through it. This is then extracted from the filter into a solution which is dropped onto the test strip.

Hydrosense Pro Ultra Rapid Legionella Water Test. Reliable and rapid self testing of water samples from any source. This  new product is just as easy-to-use and accurate as the ONE Ultra but now detects all Legionella pneumophila serogroups 1-15.

Hydrosense ONE Ultra Legionella Swab Test: Biofilms are the slimy substance that can be found inside pipework or on surfaces like shower heads, water tanks or pools. If Legionella is present, there is a strong chance it will reside in biofilm. This test kit will quickly and easily sample this substance for the bacteria to detect Legionella pneumophila serogroup 1 (LpSG1).

Hydrosense ONE Ultra Legionella Industrial Kit: If there is a need to repeat test a single water outlet in high-risk areas like commercial, healthcare and hospitality buildings with large water systems, this test kit would be the ideal choice. The test detects Legionella pneumophila serogroup 1 (LpSG1). It includes 5 tests for water sampling and the Hydrosense filter technology is delivered using the plumbing fitting adaptor (US 1/2 inch NPT and 3/4 inch BPT fittings). Simply attach the adaptor and leave it in place ready for future testing.
