Description
The OBS®-5+ monitors high sediment concentrations using
an infrared laser and a proprietary dual photo-detector system
(U.S. Patent No. 5,796,481). The NEW probe transmits sediment
concentration, depth, and wave height and period to a PC via
RS-232 or RS-485 links. It can also record data internally.
The OBS-5+ has a Windows® GUI that enables the user to
generate and store sediment-calibration tables, program data
logging and sampling schemes, and graphically display data.
Operations
Using the GUI, an operator can calibrate the OBS-5+ with sediments,
change electronic gain to optimize resolution, and create
and store in FLASH memory as many as 15 unique sediment lookup
tables for future use. Users can complete the entire calibration
process without spreadsheet calculations and curve fitting.
This new feature reduces calibration time to less than half
the time previously required.
