The HI-83414 is a multiparameter instrument that measures the most important parameters in drinking water – turbidity and chlorine.
The instrument is based on a state-of-the-art optical system which provides accurate results by minimising stray light and colour interferences. Periodic calibration with the supplied standards compensates for any variations in intensity of the tungsten lamp.
The colorimeter portion of the meter uses a 525nm narrow band interference filter for maintaining the proper wavelength in the measurement of free and total chlorine. All measurements are performed with 25mm round cuvettes composed of special optical glass to ensure maximum repeatability of turbidity and chlorine measurements.
