Multiparameter Probe    Image result for sea & sun technology gmbh


We provide various multiparameter probes from Sea & Sun Technology.

Sea & Sun Technology is a globally operating system supplier of underwater measuring technology. The multiparameter probes can record temperature, pressure, conductivity (salinity), oxygen concentration and further parameters. These different chemical and physical sensors can be assembled to the probes depending on your particular needs.

CTD Multiparameter Probe

The CTD 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 probe 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 CTD probe 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.
