Mikrostruktur Sonde MSS 90LH

The MSS90D is a version of the MSS90L which is more pressure resistant (1000m).

The multiparameter probe is made for measuring micro-scale water stratification as well as the intensity of small scale turbulence in water down to approx. 1000 m.
The MSS90D profiler may be equipped with up to 9 different sensors mounted at the bottom cap .

The microstructure measuring system comprises the MSS profiler, a special winch, a probe interface and a data acquisition computer. The probe interface is adapted to the PC (laptop or desktop) via USB port.

Standard sensor equipment:

  • Pressure transducer
  • Temperature (PT100)
  • Conductivity
  • 2 x Shear
  • Fast temperature sensor (NTC)
  • Acceleration (vibrations) – intern

Additional sensors (max.3)

  • Turbidity
  • Oxygen
  • pH
  • Redox
  • Fluorometer
  • Tilt sensor (2axis)

Beschreibung

The NEW CTD48c / CTD48Mc probes are very small and handy microprocessor controlled Multiparameter Probes for precise online measurements as well as for self-contained operation in deep and shallow water. The difference between the new CTD48c / CTD48Mc and the previous version are:

– new powerful controller
– larger memory for storing data
– calibration coefficients stored inside the probe
– output of calculated / physical data
– more and powerful interfaces
– with rechargeable batteries available ( probe must not be opened )

Due to its small size and low weight of 1.2 kg, it is particularly suited for the mounting on ROVs and bottom landers. The probe is completely made of titanium (except the screws). The housing is inert against nearly all chemical compounds and absolutely corrosion free.Due to the small housing diameter of 48 mm (including sensor protection tube) the probe can also be used for profiling in 2” boreholes.
The standard CTD48Mc allows operation in different modes:

– Time mode
– Increment mode
– Continuous mode
– RS232, FSK or Ethernet in online mode
– fast readout of stored data via USB

Time mode is the most important mode for long term measurements, where the operator selects start and stop time and the measuring time interval. Increment mode is mainly used during profiling and enables the user to carry out a great number of profiles with data reduction and without the need to upload stored data file after each measured profile.

The user selects start and end depth and increment size. The probe then stores automatically a complete data set at each increment depth.

The CTD48Mc is equipped with an 8 channel data acquisition system with 20 bit resolution. A high long-term stability and automatic self-calibration of the analogue digital converter guarantees stable and precise CTD measurements for many years.
