Optical Turbidity Sensor

Product Name: Optical Turbidity Sensor
Product brand：FLUIDINGS

Fluidings measures turbidity with a 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.
