Function and system design
                Measuring principle


                    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.

                Measuring methods


                    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



                    Measuring system


The Turbimax CUE21 / CUE22 measuring system comprises:

                    • Turbimax turbidimeter with installed cuvette and desiccant pouch
                    • Connecting tubing with
                    – fittings for flow through assembly
                    – shutoff clamp
                    – backpressure valve
                    – drain vent screw (in pressurized systems)

                    • Sensor interconnect cable

                    Installation
                    Wall mounting
                    Turbimax CUE21 / CUE22 is recommended for indoor use.
                    When mounting the instrument note the following:
                    • Check that the temperature does not exceed the maximum permitted operating temperature range
                    (0 to 50 °C (32 to 122 °F)).
                    • Leave a free area of approx. 0.20 m (8.00") above the instrument. This will ensure enough room for
                    calibration and cuvette maintenance.
                    • Mount the instrument as close as possible to the sampling point to ensure a quick response time

                        (within 2 to 3 m (6 to 10 ft)).
