Pasco Turbidity Sensor

The Pasco Turbidity Sensor measures the particles suspended in aqueous solutions in NTU (Nephelometric Turbidity Unit). The sensor can also measure precipitation or settling of suspended particles in a solution. Great for field studies or use with water filtration kits.

The Basics                                                                                These resources may be for a newer model of the sensors we offer. The function should be the same if not similar to what we offer.
