- Stop sediment sampling, measure!
- 100% calibration-free
- Measure total concentration and mean particle size at 1Hz
LISST-25X marks a generational advance in the measurement of suspended sediment concentrations and size. Unlike all prior sediment or turbidity sensors, optical or acoustic, the LISST-25X maintains its calibration over a 200:1 range of particle sizes.
This is the only sensor capable of holding calibration for sediment concentration regardless of particle color or size within this broad a range. Depending on grain size, the LISST-25X is suitable for operations in an approximate concentration range of 1 to 2,000 mg/l.
Essentially, the LISST-25X offers capabilities between those of an OBS, which suffers calibration changes due to changes in grain size or color and the LISST-100X, which provides the detailed size distribution. In short: The LISST-25X overcomes the OBS’s shortcomings, but does not provide the full size distribution of the LISST-100X.
Please note: The LISST-25X is no longer being manufactured. Contact Sequoia for more information about it potential availability in the future.
