WebThe DUSTHUNTER SP30 is a measuring device which reliably detects very low to high dust content. The measurement is based on the forward scattering of light and is independent of the gas velocity and particle charge. The automated monitoring of the zero and reference point ensures a high level of accuracy. WebIn nephelometric measurement, turbidity is determined by the light scattered at an angle of 90° from the incident beam. [4] Other methods were developed following the principle of the Jackson candle turbidimeter with improved light sources, but the bias induced by the observer was still a limitation. linfeng chen howard countyWebSurface scattering light measurement: Measuring range: 0-2 to 0-2000 mg/l: Display units: mg/l (standard) or degrees (selectable) Output range: Manual selection from 3 ranges at converter or by remote range switch.
