PBS in-situ Ammonia
The PBS is a self-calibrating ammonia analyser requiring no problematic pumping or filter systems
The PBS is a ‘wet-chemical’ analyser that is deployed directly into the sample stream. Having been the instrument of choice for several UK water companies for many years, the PBS ammonia analyser is now built in the UK, and offers highly accurate analysis even at low levels in a completely self-contained unit.
