STBD 6000

Autonomous Turbidity, Pressure and Temperature data logger.

The STBD allows to measure turbidity or the concentration of suspended particles, in coastal or estuarine environment.

It can also be used for : 
Evaluation of sediment transport 
Evaluation of suspended biomass 
Pollutant tracking 
Tracking of river runoffs in deep ocean environment using profiling.

Also available in 6000m range and with reduced measurement ranges (down to 2.5NTU).

Turbidity Sensitivity : 0 – 750 NTU, possible to measure up to 2,000 NTU. 
Other measurement ranges upon request.
