EPSA-CLW is an autonomously deployable data logger for long-term chlorophyll and turbidity measurements. The light sources
(LEDs) of chlorophyll and turbidity sensors are highly stable, minimizing the change over time. The instrument has a mechanical
wiper that periodically sweeps the optical window to prevent biological growth on it. The turbidity sensor has a good correlation with
SS (Suspended Solid) over the range. EPSA-CLW provides highly accurate and long-term stable chlorophyll and turbidity data in
oceans, rivers and freshwater.
