How to \"Assessing surface hygiene in 10s\"?
Assessing the efficacy of the surface cleaning is the first step in preventing risks in food quality management. ATP testing are widely used to evaluate the effectiveness of cleaning processes. Kikkoman. The study results evaluated the usefulness of the A3 test in monitoring the surface hygiene.
The A3 test showed a higher detection sensitivity compared with the conventional ATP test (a study by GBAC STAR of the global cleaning industry association in September 2023.

So, what is the principle of this A3 measuring device?
1. What is ATP
ATP is found in all living organisms. Intracellular ATP is mainly used to drive processes that require energy in the cell. ATP testing is one of the methods that can be used to quickly evaluate the effectiveness of the surface hygiene.
2. The limitation of the conventional ATP measurement compared with the A3 test
However, the conventional ATP tests have a limitation that ATP is degraded into adenosine diphosphate (ADP) and adenosine monophosphate (AMP) by heat, acid/alkali, and enzymes. Meanwhile, the A3 test, with the combination of two enzymes, pyruvate kinase and pyruvate phosphate dikinase, can convert ADP and AMP back into ATP, making the measurement reflect the overall dirt level more completely.
The three forms of ATP – ADP - AMP
Operating the Lumitester A3 meter is very simple
To use the device, you need to perform the following steps: the sampling cotton swabs and the measuring device Lumitester.
By the traditional method, checking with the naked eye to assess how clean a surface is, the result depends heavily on the person performing it.
Conclusion
With the device Lumitester Smart, the user can monitor hygiene in 3 easy steps within 10 seconds. The exterior design and the software interface are both intuitive. The hygiene testing is also displayed by the software through intuitive charts. From this, you can know the days/times when the highest dirt levels appeared and see how the cleaning effectiveness changes over time.
