Parameters
Learn the importance of environmental parameters, typical concentrations, influencing factors and abnormalities.
Measurements
Understand the principles of operation behind various methods used to measure and monitor environmental parameters.
Equipment
Learn about various sensors, meters and data acquisition systems used in environmental measurements.
Algae, Phytoplankton and Chlorophyll
Chlorophyll is a color pigment found in plants, algae and phytoplankton that is used in photosynthesis and allows plants to absorb energy from sunlight.
Turbidity, Total Suspended Solids & Water Clarity
Turbidity is a measurement of water clarity and quality that is determined by the amount of light scattered by suspended solids and dissolved colored material.
Dissolved Oxygen
Dissolved oxygen refers to the level of free oxygen present in water. Levels that are too high or too low can harm aquatic life and affect water quality.
Measuring Streamflow
Streamflow measurements describe the amount of water flowing through a stream or river over a fixed period of time. This is measured through stage discharge.
Measuring Dissolved Oxygen
Electrochemical or optical dissolved oxygen sensors are the modern and most precise way to measure dissolved oxygen. Other methods include colorimetry and titration.
Measuring Turbidity, TSS, and Water Clarity
Turbidity is caused by particles and colored material in water. It can be measured relative to water clarity or directly with a turbidity sensor or turbidimeter.
Buoy Mooring
Buoy mooring ensures that the floating monitoring system remains stationary. Buoy systems use single- or two-point mooring based on application-specific factors.
Online Datacenter
An online datacenter is the easiest way to share and view environmental data, providing instant access to current and historical data in tables or trending graphs.
Scour Monitoring Equipment
Scour monitoring methods commonly include sonar instruments, magnetic sliding collars or float-out devices. These methods measure elevation changes in the streambed.
Monitoring Turbidity at Dredging Sites
Monitoring turbidity at dredging sites is vital to minimizing environmental impacts, like the re-suspension of sediments, and maintaining safe water quality levels.
Monitoring Dissolved Oxygen at Hydropower Facilities
Hydropower dams provide renewable energy, but also affect water flow and quality. Monitoring dissolved oxygen ensures acceptable levels for aquatic life in the area.
Monitoring Scour at Bridges and Offshore Structures
Monitoring scour can help prevent disasters at bridges and offshore structures. Eroding sediment alters the elevation of a riverbed and can affect structural safety.
