Micrologger
A marine environmental data logger designed to monitor suspended sediment climate for long durations and at high sampling frequency with long sample bursts
Complimentary pressure (tides and waves), temperature and conductivity sensors enable a full interpretation of the suspended sediment timeseries. Other auxiliary sensors e.g. oxygen or a fluorometer can be added.
