Introducing the Hydrosense One Ultra Legionella Water Test, the most sensitive and flexible Legionella test kit for water available on the market today. With innovative technology, this kit allows testing of water samples from any source for the presence of Legionella pneumophila sg1 antigen - the species responsible for over 90% of Legionnaires' disease cases.

With its unique filter technology, the Hydrosense One Ultra captures bacteria as the water sample is pushed through, delivering highly accurate and reliable results that are recommended for high-risk areas such as cooling towers, water tanks, fountains, showers, sinks, spas, and pools.

This fast, reliable, and accurate Legionella test kit has a sensitivity of 100 CFU/L, making it the world's fastest on-site Legionella test, delivering results in just 25 minutes. In addition, it can detect dangerous Non-Culturable (VBNC) bacteria, something that lab culture cannot.

This kit is designed for ease of use, allowing anyone to carry out the tests with minimal training.

How to use the Hydrosense One Ultra (step by step guide)


Step 1 : Collect water sample.

Using the collection beaker provided, fill the beaker to the 250ml mark with the sample fluid to be tested.


Step 2 : Draw sample into syringe.

Transfer up to 60ml of the fluid from the beaker into the syringe.


Step 3 : Attach syringe to filter and push through sample.

Screw on the included filter and push the sample through. Repeat this step until all 250ml of sample has been flushed through the filter then disconnect the filter. Remove the cap and attach it to the opposie side of the filter.


Step 4 : Attach the buffer syringe.

Remove the cap from the buffer syringe and attach it to the filter. Push all the buffer solution into the filter then backwash it (draw it back). Do this 3 times. Once complete make sure the buffer syrning contains 0.1mm of solution without air bubbles then unscrew the filter.


Step 5 : Apply the sample to a Hydroseonse one ultra test.

Open a new hydrosense one Ultra test and apply the 0.1ml of buffer solution to the sample window. After 25 minutes, the sample is ready to read. Any line under the 'T' section should be treated as a positive result. If no control line is present, perform a retest of the sample using a new Legionella Ultra test.

How the Hydrosense One Ultra test works

The Hydrosense One Ultra Legionella Water Test kit utilizes a highly effective Lateral Flow Immunochromatographic Assay (LFICA) test. This method uses Legionella antibodies which are tagged with red nanoparticles. These antibodies bind to any bacteria present in a water sample or on a surface and make them visible on a line on the device. The test specifically detects Legionella pneumophila serogroup 1 (LpSG1), which is responsible for 70-92% of Legionnaires' disease cases.

With just a 25-minute wait time, the test delivers qualitative results indicating the presence or absence of the bacteria. The test operates similarly to a pregnancy test where one line represents a negative result and two lines indicate a positive result.

Furthermore, our test results can be conveniently managed and stored via our Hydrosense Smartphone App. You can also print a certificate for conducting the test through our secure Hydrosense Pro Portal. Choose the Hydrosense One Ultra Legionella Water Test kit for fast, reliable, and easy-to-read results you can trust.

Why Choose the Hydrosense One Ultra?

The Hydrosense tests were developed and independently validated for use in high-risk areas, such as cooling towers, water tanks, domestic hot and cold-water systems, sinks, showers, decorative fountains, whirlpool spas, pools and many more. Their incredible convenience, speed and ease of use make them the first choice for companies where reputation is crucial, where customer and employee safety are paramount, where clients are vulnerable (in care facilities or hospitals for example) or where facilities are in remote locations. The Hydrosense testing method, when combined with the latest smartphone technology, offers a significantly improved protection profile for employees, customers, and the general public.
