Logger version chlorophyll and turbidity sensor with wiper INFINITY-CLW ACLW2-USB

Infinity-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 to inhibit biological growth on the optical window. The turbidity sensor has a good correlation with SS (Suspended Solid) over the range. Infinity-CLW provides Highly accurate and long-term stable chlorophyll and turbidity data in oceans, rivers and freshwater.
