Attention to the suspended sediment issue is a fundamental subject in the regional and strategic programming. In the other hand, lack of proper database of this phenomenon has been causing serious problems. By developing in the societies, it is expected increasing pressure on the natural resources, flooding events and sediment removal in the near future. So the need to enhance sediment database is essential. In order to enhance sediment database in hydrometric stations of Iran, in the present study, optical suspended sediment sampler instrument was constructed and calibrated in the laboratory and field conditions. Laboratory calibration was done in two stages, including high and low sediment yield flows. Calibration curves drawn for this process, represents a very good correlation between the actual and the estimated suspended sediment data. The R² statistic for low and high sediment concentration and is 0.995 and 0.98 respectively. The field validation test of device was carried out in Mehriz River in the Yazd province of Iran, and indicated the appropriate performance of the instrument.
