WQS Water Quality Sampling System
WQS Water Quality Sampling System

YSI's Water Quality Sampler System includes a rugged sampler with a peristaltic pump and a 2-gallon polyethylene sample bottle. The system features a display showing sensor data, relay states, and programmable threshold levels for alarms or sampling triggers. The data recorder logs water quality readings and sample times, with easy access to data via PC software.
