Download the Fact Sheet Now! The amount of dispersed suspended solids in natural water bodies is an important indicator of water quality. These solids that often include silt, clay, algae, organic matter, and other minute particles, obstruct the transmittance of light through the water and impart a qualitative characteristic known as turbidity. Turbidity is often closely correlated to climatological or surface water conditions and changes in turbidity are therefore indicators of changes in environmental conditions. “Turbidity data can be used as a surrogate measurement because it is strongly correlated with sediment, nutrients and bacteria, and can be measured in-stream on a continuous basis.” Topics Discussed in Fact Sheet: Turbidity Measurement Technologies Common Turbidimeter Design Criteria Variability Based on Measurement Method Download the Fact Sheet!
Download the Free Technical Note: Algae Measurements Using In Vivo Fluorescence! Phytoplankton are microscopic, free-floating photosynthetic plants and bacteria that are commonly found in surface waters throughout the world. Aquatic scientists and water resource managers measure phytoplankton to gain a more in depth understanding on ecological dynamics, ecological health, nutrient status, and harmful algal bloom potential in aquatic systems. Submersible fluorescence sensors help to make this measurement easy, efficient, and economical by enabling real-time field estimates of phytoplankton biomass that can be directly correlated to quantitative laboratory measurements using standard methods.

Water Level Measurement Practical and Reliable with the OTT RLS. The OTT RLS is a non-contact radar level sensor with pulse radar technology. The OTT RLS offers a large measurement range with a small blanking distance and narrow beam width and it easily connects to most dataloggers. The RLS has extremely low power consumption and is ideal for remote or solar powered sites.
