Microstructure profiler

MSS profiler (Photo) are multiparameter probes for the measurement
of microstructure and turbulence in marine and limnic waters.
They are equipped with high resolution microstructure and
standard hydrographic sensors. The MSS profiler are manufactured
in co-operation with Sea&Sun Technology GmbH.




MSS60:

Light weight instrument for measurements in high turbulent environments.
Designed for use from small boats.
MSS90/90L:

All round instrument for general use.
Can be used for rising measurements
MSS90-D:

Heavy profiler for deep sea measurements and measurement in low turbulent environments.
