Turbidity probe for the measurement of suspended solids, available in a high or low turbidity version.
The probe for the high turbidity (mod. AT) using the method of the detection of the light reflected back by the
particles in suspension (back scattering). It is used an infrared light source so as to be independent of the
color of the sample. The light pulse, is sent through a lens in the sample, the light, reflected from the suspended
particles falls within the probe through a second lens and converted into a signal electric, according to the
concentration and the particle surface.
For measurement applications in clean water, or at least a little murky, it is recommended to use the BT version
This type of sensor uses the nephelometric method according to ISO 7027, and can be used for both
applications in the pipe and underwater. The turbidity measurement is carried out by the method of diffusion
light operated by suspended particles in the sample. A beam of light is sent into the sample through a window
transparent to the wavelength used. The proportion of light scattered with an angle of 90° from particles
suspended in the sample falls within the probe through a second optical window.
