In a world’s first, Sequoia Scientific, Inc. has invented a method (patent pending) to pair turbidity data with their acoustic backscatter sensor; the LISST-ABS. This pairing of acoustic and optical data leads to a radically-improved estimate of Suspended Sediment Concentration (SSC), compared to that which either sensor can provide on its own. In fact, measurements of SSC with this new method are within a factor of 2 of the actual value (e.g. based on sampling and subsequent filtration).

This is an order of magnitude improvement over currently used technologies.

To get this incredible innovation into the hands of the world, Sequoia is introducing a new instrument system, the LISST-AOBS Super-Turbidity Meter.

What’s more, all existing LISST-ABS sensors can be expanded to the LISST-AOBS Super-Turbidity Meter. Also, all existing turbidity sensors can be expanded to the LISST-AOBS Super-Turbidity Meter.

The implications of the new method and the introduction of the LISST-AOBS Super-Turbidity Meter are two-fold:

1) Existing regulations (e.g. for stormwater, construction, environmental monitoring) that call for the monitoring of turbidity can be adhered to while…

2) the user – at the same time – can obtain an accurate estimate of SSC.

The impact of this new technology is sure to be huge. According to the United States Environmental Protection Agency, excessive sediment is the leading cause of impairment of the Nation’s waters. High SSC values influence virtually all aspects of aquatic life in a detrimental manner. So accurate measurements of SSC with low-cost sensors that can be deployed for months or years are will bolster a wide range of environmental quality programs, remediation efforts, court cases and more.

The LISST-AOBS Super-Turbidity Meter can help provide the data needed to make the decisions that will protect the World’s waters.
