Sampling point
Requirements of the sampling point:
Caution!
• Do not connect the sampling hose to pressurised systems.
• Use the suction filter to impede coarse and abrasive solids and solids which can cause clogging.
• Immerse the suction hose in the direction of flow.
• Take the samples at a representative point (turbulent flow; not directly at the bottom of the chan-
nel).
Useful sampling accessories
• Suction filter:
Impedes the entry of coarse solids and solids which can cause clogging.
• Immersion assembly: the adjustable immersion assembly fixes the sampling hose at the sampling
point.
