Sectie 9: Monstervereisten voor gevaarlijke omgevingen.
Het monster mag niet onder druk staan en moet zodanig worden geplaatst dat het niet continu de BioTector kan overstromen als er een buisje zou breken
in de BioTector B3500-analyser. In de onderstaande tekening wordt een typisch voorbeeld getoond.
Sample requirement for Hazardous Areas:
The sample must not be under pressure, and installed so that it cannot continuously
BioTector
flood the BioTector in the event of a tube breaking inside the BioTector analyzer.
A typical example is shown in this drawing.
