YOUR ESSENTIAL TOOL FOR SEDIMENT INSIGHT

The DeepSizer 300 is a submersible particle size analyzer for real-time sediment monitoring in rivers, lakes, estuaries, and coastal waters. It measures concentrations from 0.001 to 100 g/L and particle sizes from 0.1 to 2000 μm with high accuracy.

Powered by six core technologies—including two patented innovations, Differential Path and Adaptive Path Technologies—it adapts to diverse conditions and remains reliable even in extreme environments.

DeepSizer 300 overcomes the risks, delays, inaccuracies, and maintenance burdens of traditional sediment analysis. It delivers trusted insights for sediment studies, ecological monitoring, water-quality assessment, and hydraulic engineering— supporting resilient, sustainable water systems.

Safer In-situ
Measurement

Challenge: Traditional sampling is labor-intensive, time-consuming, and exposes personnel to potential health and safety risks.


Solution: DeepSizer 300 enables direct in-situ measurement, cutting sampling risks and providing reliable, continuous data for ecosystems, pollutant tracking, and water safety.

Real-time Sediment Monitoring

Challenge: Conventional methods are too slow to track short-lived spikes in sediment concentration during floods and typhoons.


Solution: DeepSizer 300 provides real-time measurements of concentration and PSD, capturing critical flood events to support early warning and protect communities.

Accurate Results in High Turbidity

Challenge: Common optical and acoustic methods lose accuracy in highly turbid waters, limiting their reliability for sediment management.


Solution: DeepSizer 300 combines adaptive sediment concentration measurement with advanced multiplescattering correction, ensuring accurate results even under extreme sediment loads.

Reliable Long-term Field Deployment

Challenge: Extended field campaigns often suffer from window fouling, biofilm growth, and sediment deposits, leading to poor data quality and high maintenance costs.

Solution: DeepSizer 300 features automatic window cleaning and intelligent background correction, enabling long-term unattended operation with high-quality data.
