Optima CVE-16 All Season Refrigerated Composite/Sequential Vacuum Wastewater Sampler

Wide range of bottle configurations and QCEC reliability

Optima CVEThe model Optima CVE-16 is a heavy duty, All Season refrigerated composite/sequential vacuum wastewater sampler. With a fiberglass base and body, the All Season unit is suitable for corrosive environments and severe outdoor conditions. It 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 pulse. 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.
