Description

Multiparameter Probe CTD 48M

The CTD48M probe is a very small and handy microprocessor controlled multiparameter memory probe for for limnologic and oceanographic measurement with up to 4 sensors and for depth up to 6000 m. It measures conductivity, temperature, pressure and one optional parameter.

Data are stored in a standard flash memory card with a capacity limited to 128 Mbytes by the internal firmware. Up to 3 000 000 CTD data sets can be recorded on this memory.

The CTD 48M allows operation in different modes:

  • Continuous mode: each data set is stored.
  • Time mode: data sets are only stored at programmable intervals with several selectable schemes.
  • Increment mode: data sets are stored at programmable depth increments, up to 255 files can be stored without the need for data retrieval in between
  • Online mode (RS-232 – on multiconductor cables)

The CTD48M is equipped with a 4 channel data acquisition system with 20 bit resolution. Data output is 16 bit. 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.

Calculated parameters:
