Sea & Sun Technology CTD60Mc – ultra deep sea
$ 0,00
The CTD60Mc – ultra deep sea is a high quality, high accuracy memory probe for oceanographic measurement of conductivity, temperature, ambient pressure in depth up to 11000 m (12000 dbar)
The CTD60Mc – ultra deep sea is characterised in particu¬lar by its ability to directly output physical and calculated data such as salinity, sound velocity and density
Description
The CTD60Mc – ultra deep sea probe is a small and handy microprocessor controlled multiparameter memory probe for oceanographic measurement with up to 3 sensors and a maximum depth down to 11000 m. It measures electric conductivity, water temperature and ambient pressure.
Data are stored in a standard flash memory with a capacity of 128 Mbytes. Up to 5,5 million CTD data sets can be recorded on this memory
Online operation
This mode is possible up to 350m via RS-232 Interface, but not recommended for this Probetyp. Only for testing.
Memory operation
The memory operation is divided into the following operation modes:
- Continuous mode: each data set is stored.
- Time mode: data sets are only stored at programmable intervals with several selectable schemes.
- Pressure mode: data sets are stored at programmable depth steps.
The CTD60Mc – ultra deep sea is equipped with a 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.
The probe power supply is activated by touching a reed contact with a magnetic rod. LED displays power supply status and optical control of memory access.
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 shared graphic user interface. The “SST-SDA” is a part of our shipment.
