The model Optima-QLS 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. This sampler 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 28 feet. This unit uses a self learning smart sampling system. A two year warranty is standard.
