Product Description
The PS-2122 Turbidity Sensor is designed to measure the
turbidity level (“cloudiness”) of water samples in nephelo-
metric turbidity units (NTU) by measuring light scattered
by the sample at 90 degrees. The light source is stabilized
to prevent drift. The opaque housing eliminates ambient
light.
The Turbidity Sensor is intended for educational purposes
and is not recommended for environmental compliance
testing or similar activities.
