OBS-5+ High Suspended Sediment Concentration Monitoring System
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.
Features
Measures concentrations up to 500 g/l (specific gravity 1.30)
Logs instrument depth
Records 200,000 scans of data in FLASH memory
Runs as long as six months on three alkaline C cells
RS-232 and RS-485 data links
Compact package 380 mm (15') by 60 mm (2.4')
Applications
Monitor dredging & mining operations
Survey contaminated sediment
Determine dredge efficiency
Sediment transport research
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.

Ranges
Sediment Concentration: 50-500 g/l (sp. gr. 1.30)(range depends on sediment type)
