Optical Turbidity Sensor

Product Name: Optical Turbidity Sensor V2.0
Product brand：FLUIDINGS

Fluidings measures turbidity with an fiber optics sensor. An 860nm light from the emitter enters the sample via fiber and scatters off particles in the water. The scattered light at 90 degrees, enters a PD
detector via fiber. This follows the nephelometric technique of measurement, and values are expressed in nephelometric turbidity units (NTUs). It follows the ISO7027 standard.
