CRP Vessel Mounted Single Sampler

Vessel Mounted Single SamplerVessel Mounted Singel Sampler

The vessel mounted sampling system is generally connected to a dip pipe at the top of a process vessel. The sample is drawn up from the vessel through the dip pipe and into the sampling system. It is isolated within the sight glass chamber where it can be dispensed into a sample bottle.

Product Description

Typical construction:

• Small bore PTFE tube running down through centre of dip pipe
• Lower manifold
• Isolation Valve
• Centre manifold with outlet valve, cabinet and threaded bottle  connector
