SD204

The SD204 calculates and records salinity, temperature, depth, sound velocity, and water density.

Therefore, the SD204 is often recognized as a sound profile.

Optional sensors can be added, e.g., dissolved oxygen, fluorescence, and turbidity. For optional sensors with multiple sensitivity ranges, the SD204 features automatic range switching. Data is recorded in physical units.

The accompanying software, SD200W, includes versatile functions for programming, processing, and presenting both post and real-time data: – Multi-graph, online plotting, density, and depth calculations (weight profile).

This program is continuously updated based on customer requests. Program settings and calibration coefficients are stored in non-volatile EEPROM and remain unchanged in case of power loss. Strength and complete protection against leaks are achieved through electronic vacuum molding and other components in solid polyurethane.
