The MINI STD models SD202/203 are self-contained instruments that measure, calculate and record in situ the sea water conductivity, salinity, temperature, pressure and sound velocity. Two optional sensors can be added: Dissolved oxygen and fluorescence, or customer specified sensor. Except for data storage capacity, all specifications are the same for the two models.

The power consumption is extremely low. Practically speaking the battery capacity is sufficient for a year-around operation. Data recorded in the instrument are in physical units and can be copied to a PC and presented immediately after the measurements of the MINI STD comparable to much more voluminous and expensive cable based STD-systems.


MINI/STD in standard packing.
Interfacing of customer specified sensors offered.

This is all you need to produce professional STD/CTD profiles and time series on your own PC.
The suitcase contains:

- On/Off magnetic key
- PC communication cable
- PC program diskette (Windows)
- Operating manual / Calibration report
