Measuring range
0 - 1000 NTU
Measuring principle
Turbidity measurement using standardised 90° scattered light method acc. to U.S.EPA 180.1(White Light)
Design
The transmitted infrared light beam is scattered by the solid matter particles in the medium. The scattered light beams are detected by scattered light receivers which are arranged at an angle of 90° to the light source.
