Smoke density measurement
WebBy convention, smoke density is expressed on a per meter basis (m-1). The smoke density is a function of the number of smoke particles per unit gas volume, the size distribution of the smoke particles, and the light absorption and scattering properties of the particles. WebThe measurement of density is crucial in different industries to ensure quality for both raw materials and finished goods. For example, the density of ultrapure water at 20.00 °C is known to be 0.998203 g/cm 3: any deviation from this value ± tolerances would imply that the water sample contains impurities.

As proposed in 1888, there was no definitive chart, rather, Prof. Ringelmann provided a specification for how to draw them; where smoke level '0' is represented by white, levels '1' to '4' by 10 mm square grids drawn with 1 mm, 2.3 mm, 3.7 mm and 5.5 mm wide lines and level '5' by all black.
