Turbidity measurement For turbidity measurement a light beam is sent through the medium and is diverted from its original direction by optically denser particels, e.g. solid matter particles.

90° WL scattered light method The measurement uses the standardised 90° scattered light method acc. to U.S. EPA 180.1. The turbidity of the medium is determined by the amount of scattered light. The transmitted white light beam is scattered by the solid matter particles in the medium. The scattered beams are detected by scattered light receivers which are arranged at an angle of 90° to the white light source. 90° NIR scattered light method The measurement uses the standardized 90° scattered light method acc. to ISO 7027 / EN 27027. The turbidity of the medium is determined by the amount of scattered light. The transmitted light beam with a wavelength in the near-infrared range is scattered by the solid matter particles in the medium. The scattered beams are detected by scattered light receivers which are arranged at an angle of 90° to the infrared light source
