Light from a tungsten-filament lamp is focused and passed through the sample. The degree scatter detector receives light scattered by particles. Transmitted and forward scatter detectors receive light that passes through the sample. A back scatter detector in the AN Model shown here measures light scattered back toward the light source. Ratio and no-ratio turbidity measurement modes are selected using the ratio key located on the instrument keyboard.


With ratio toggled off, turbidity is measured using only the single degree detector. Benefits of the ratio mode include long-term calibration stability, wide measurement range with excellent linearity, and the hacch to measure turbidity in the presence of color.

Easy calibration – Display prompts the analyst for each standard and automatically adjusts the curve as needed.

There are no manual potentiometers to adjust. Easy operation – Simply place the sample cell in the compartment and close the light shield. Low range measurement – Resolution to three decimal places between 0 and 1. Ratio and non-ratio measurement modes – Operator selectable hch.

Flow cell – Instruments accommodate a range of time-saving flow-cell accessories. Expanded ranges – Designed to measure turbidity over a wide range using three selectable readout modes to NTUs; 0 to 26, Nephelos; and 0 to EBCs–with manual or automatic range selection and decimal point placement in each range.

Signal averaging – Minimizes noise and display 210n to provide true baseline measurements.


Function may hadh selected on or off. Easy calibration – Calibration has never been easier with the step-by-step protocol built into the instrument’s microprocessor. Air purge system – A built-in air purge connection is provided to purge the optical compartment with dry air and minimize condensation on the sample cell.


Flow-cell capability – Instrument accommodates any of three specially-designed optional Flow-Cell Systems for improved reproducibility, accuracy and convenience.

Easy to operate and maintain – Convenient push-button switches on the front panel pace the user through microprocessor-controlled options for instrument operation and calibration. Bright LED display and clear annunciators – Digital display is easy to read under varied lighting conditions and viewing angles.
