Vernier GO DIRECT® TURBIDITY SENSOR. Use the Go Direct Turbidity sensor to measure the turbidity of freshwater or seawater samples and determine water quality. Ideal for performing experiments in aquatic science, earth science, environmental science and natural resources. Measures in NTU (Nephelometric Turbidity Units, the standard unit used by most water collection agencies and organizations).

The small, sleek design and simple setup make it easy to use in the field or in the classroom.

Use to perform the following kinds of experiments:

  ACSBL021 - Biodiversity and the interconnectedness of life - Describing biodiversity - In addition to biotic factors, abiotic factors including climate and substrate can be used to and classify environments
  ACSBL029 - Biodiversity and the interconnectedness of life - Ecosystem dynamics - Models of ecosystem interactions (for example, food webs, successional models) can be used to predict the impact of change and are based on interpretation of and extrapolation from sample data (for example, data derived from ecosystem surveying techniques
  ACSSU176 - Biological Sciences - Ecology - Ecosystems consist of communities of interdependent organisms and abiotic components of the environment; matter and energy flow through these systems
