General Description

The OBS-5+ System monitors high sediment concentrations using an infrared laser and a proprietary dual photo-detection system (U.S. Patent No. 5,796,481). The probe transmits sediment concentration and depth to a PC via an 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, log data, program logging/sampling schemes, and graphically display data.

Using the Windows GUI, an operator can calibrate the OBS-5+ with sediments, change electronics gain to optimize resolution, create as many as 15 unique sediment lookup tables, and store those tables in FLASH memory for future use. Users can complete the entire calibration process without spreadsheet calculations and curve fitting.
