How the aquaBio-B503 works
The aquaBio continuous water meter, unlike other devices, works like this:
- It does not require adaptation of results and provides results comparable to laboratory standards.
- It quantifies results in MPN/100ml based on ISO 9308-2.
- Handles a sample volume of 100 ml as specified by the standard.
- No dilution required except with seawater, which is handled automatically.
- With accurate dosing facilitated by a CCD camera and ETV ISO 14034 verification, aquaBio ensures reliable and accurate results for informed decision making.
- It provides results so that you can have continuous information on microbiological water quality by detecting the end of a contamination episode much earlier than the laboratory.
- It has different and flexible sampling options, including episodic sampling that tracks the recovery of the contamination alert as soon as adequate quality is restored.
