Online and memory probe
The CTD90M is a high quality, high accuracy online multi parameter probe with max. 9 sensors for oceanographic and limnological measurement of physical, chemical and optical parameters for depth up to 6000 m.
The CTD90M is a high quality, high accuracy multi parameter probe for oceanographic and limnologic measurement of physical, chemical and optical parameters with up to 9 sensors and for maximum depth up to 6000 m.
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 actual number depends on the selected storage options and the number of sensors adapted to the probe.
The CTD90M allows operation in different modes:
The CTD90M is equipped with a 16 channel data aquisition system with 16 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 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.
The power supply of the probe is activated by touching a reed contact with a magnetic rod, LED displays power supply status and optical control of memory access.
