LISST-ABS

Sequoia Scientific

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.


- The 8MHz acoustic sensor ‘sees’ all size grains, and unlike OBS, it sees coarse grains very well.
- 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).
- Operates over a ~5-decade working range in concentration!
- Tolerates fouling.

The LISST-ABS is easy to integrate into existing sensor platforms. Click here for simple version of how it works, or here to get a detailed explanation.
