OBS-5+ System

7. Calibration

7.1 Sediment and NTU Calibration

In addition to the concentration, the size, shape, and reflectivity of suspended

sediment particles vary from one location to another and will influence OBS-

5+ measurements. When these sediment characteristics change, they will

produce apparent changes in SSC by themselves unless sediment calibrations

are performed. All sediments produce a unique set of calibration curves like

the examples shown in FIGURE 4-4. The sediment calibration procedure is

complicated, and for a modest fee, we will calibrate an OBS-5+ sensor with

your sediment. Call for a quotation to perform this service.
