Indoor Wall Mount Composite Vacuum Wastewater Sampler                           

Wide range of bottle configurations and QCEC reliability

Wall Mount CVEThe CVE-16-WM  and WM-QLS wastewater samplers are wall mounted vacuum wastewater samplers. Each relies on proven vacuum pump technology to deliver high sample integrity and reliable performance. The vacuum pump exceeds EPA transport velocity requirements and generates a stronger purge. The maximum vertical lift is 23 feet on a standard unit, and 28 feet is available as an option. A two year warranty is standard.
