OBS501 Turbidity Probe with Antifouling

 

OBS501 Turbidity Probe with Antifouling

The OBS501 features dual backscatter and sidescatter sensors, a shutter mechanism that keeps the lenses clean, and a refillable biocide chamber that prevents fouling–just like the OBS500. In addition, the OBS501 has improved performance in heavy sediment load environments.
