Where there’s water, there is opportunity for microbiological contamination, so it is important to conduct regular tests to monitor hygiene. These monitoring systems measure the hygiene status of a sample within seconds, with on-site detection of microorganisms or organic residues. Extremely compact instruments are ergonomically designed to be lightweight and allow for portable testing. Simple tests can be applied in the fields of food industry, catering, dairy industry, health authority, and laboratory research.
