Century 3000-QLS Indoor Refrigerated Composite/ Sequential Vacuum
Wastewater Sampler

Wide range of bottle configurations and QCEC reliability

Built tough for tough duty, the Century 3000-QLS is our refrigerated vacuum wastewater sampler. 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 purge. The maximum vertical lift is 28 feet. This unit uses a self learning smart sampling system. A two year warranty is standard.
