Vernier® Turbidity Sensor

Use the Turbidity Sensor to measure the turbidity of freshwater or seawater samples. Its small, sleek design and simple setup make it easy to use at the collection site or when you return to the classroom. The Turbidity Sensor measures turbidity in NTU (the standard unit used by most water collection agencies and organizations). Calibration can be done in about one minute using a high quality Hach StablCal® 100 NTU standard (included). Also included is a high-grade glass cuvette for the water sample to be measured.

Chemistry and biology teachers can also use this sensor to monitor precipitates formation or algae and yeast populations.
