Multiparameterprobe CTD 60M | Multiparametersonde

The CTD60M is a high quality, high accuracy multiparameter logging probe for oceanographic and lim-nologic measurement of physical, chemical and optical parameters in up to 2000 m water depth. The probe can be equipped with maximum five sensors mounted on the bottom cap. SST´s CTD60M runs from an internal battery and records data at programmable time intervals or pressure levels in a non volatile FLASH memory with a capacity of 8 Mbytes. A standard RS-232 inter-face is used for programming, tele-metry output and data read-out. The supplied Standard Data Acquisition Software package “SST-SDA” includes the handling of the logging process and the display of online or recorded data with a common graphic user interface.
The online version of the probe, the CTD60, is able to control and operate motor driven water-sampler rosettes (Hydro-Bios).

The CTD60 allows the simultaneous measurement of following parameters:

  • Pressure (depth)
  • Temperature
  • Conductivity
  • pH
  • Redox
  • dissolved oxygen
  • Light transmission
  • Light scattering (90°)

Other sensors on request.
All sensors are protected by a titanium cage.

Recording modes

Continuous mode
Each data set is stored.

Time mode
Data sets are stored only at programmable intervals with several selectable schemes.

Pressure mode
Data sets are stored at programmable depth stamps. More than 200 casts can be stored at profiling and continuous mode as long as the flash-memory or battery capacity is sufficient. The start of a cast is possible using a magnet, the probe must not be connected to a computer. Up to 250000 CTD data sets can be recorded, the actual number depends an the selected storage options and the number of sensors adapted to the probe.
