Detection of Microorganisms and Bacteria Level

Hygiena ATP Meter & ATP Test

For those sensitive areas like homes, schools, nurseries and, health institutions (i.e. clinics), ATP Test provides a quick way to detect microorganisms. This is how Hygiena ATP Meter works quickly (a few minutes) to verify if surfaces have been cleaned thoroughly and free from living organisms like bacteria or moulds.In the other hand, conventional Incubation technique for bacterial growth may take a few days to complete.

Testing Method

Press the swab, holding only the stem of the swab, firmly against the test area and rub vigorously, rotating the swab while covering the whole area. Put the casing in the ATP Luminometer and wait for 15 seconds to calculate the bacterial level (0 – 9999).
