TEST LIKE A PRO
Legionella pneumophila causes over 97% of Legionnaires’ disease1, a potentially deadly pneumonia. 10% of people who contract this disease lose their lives.
Our easy-to-use Legionella test kits detect Legionella pneumophila antigen in water samples and biofilms. The results are delivered within 25 minutes and are highly accurate.
Our most comprehensive tests detect Legionella pneumophila serogroups (sg) 1-15 in levels as low as 100 CFU/L (0.1 CFU/ml) in water and 200 CFU per swabbed area.
THE PRO RANGE
Our most comprehensive range, detecting all Legionella pneumophila serogroups 1−15 with clear sg 1 and sg 2−15 differentiation. Ultra−sensitive water and biofilm testing with defined action levels for confident decision−making.

This advanced one-time-use kit uniquely detects all serogroups (1−15) of the most dangerous Legionella species, Legionella pneumophila in just 25 minutes. Easy−to−use test; it can be carried out by anyone in any setting and requires minimal training. Our visual instructions provide a simple step by step guide.
| Sensitivity: | 100 CFU/L |
| Tests included: | 1 |
Our comprehensive and sensitive Legionella swab test is designed for testing surfaces and biofilm. The process involves collecting a sample through swabbing areas where biofilm accumulates e.g. shower heads, taps, storage tanks, pipework and the water edge of pools or hot tubs.
| Sensitivity: | 200 CFU per swabbed area |
| Tests included: | 1 |


Perfectly designed for water outlets needing repeat testing and includes everything needed to complete 5 tests. It uses our exclusive Hydrosense filter technology, enabling the isolation of bacteria through conventional plumbing connections. The pipe fitting also conveniently connects directly to standard shower hoses.
| Sensitivity: | 100 CFU/L |

Why choose Hydrosense?

It’s the worlds fastest on-site Legionella test.

It delivers test results in 25 minutes.

Detects Legionella pneumophila serogroups 1-15, which account for 97% of Legionnaires’ disease cases.

It can detect dangerous VBNC Legionella (Viable but Non-Culturable), something lab culture cannot.

Anyone can carry out the tests with minimal training.

It gives real-time results – you don’t have to wait several weeks for lab reports.
