Sequoia Scientific, Inc. is proud to offer the first low-cost acoustic backscatter sensor designed specifically for measuring Suspended Sediment Concentration at a point. This is a new type of sediment sensor, superior to turbidity or optical backscatter sensors (OBS) for 4 reasons.


  1.         The 8MHz acoustic sensor ‘sees’ all size grains, and unlike OBS, it sees coarse grains very well.
  2.         The LISST-ABS calibration is far less sensitive to grain size changes than OBS sensors, changing only ~ ± 30% over 30-400 microns (see Application Note).
  3.         Operates over  a >4-decade working range in concentration!
  4.         Tolerates fouling.
