90° scattered light method
Measurement is performed with a wavelength of 860 nm, as described in ISO 7027/EN
27027.
The emitted light beam is scattered by the solid particles in the medium. The scattered
radiation generated in this way is measured by scattered light receivers, which are
arranged at an angle of 90° to the light sources. The turbidity of the medium is determined
by the amount of scattered light.

135° backscattered light method
The emitted light beam is scattered by the solid particles in the medium. The
backscattering generated is measured by scattered light receivers, which are arranged next
to the light sources. The turbidity of the medium is determined based on the quantity of
back-scattered light. It is possible to measure very high turbidity values with this type of
scattered light measurement.
