JC-LB Ringelmann flue gas blackness chart product overview: By comparing the smoke color at the outlet of the emission source with the Ringelmann smoke concentration diagram, when a certain exhaust color is close to the color block, it is considered that the smoke density is consistent with the blackness level of the color block. It makes the test of smoke blackness simple and convenient, and at the same time ensures the accuracy of the monitoring work. Therefore, the product can be widely in the measurement of smoke blackness in various environmental protection departments and various industrial and mining enterprises. By measuring the blackness of the flue gas, the air pollution degree of the flue gas emissions and the fuel combustion utilization rate can be analyzed, so as to provide an effective monitoring method for environmental management and energy saving. This product can be placed on a tripod for observation or handheld use. 2. Working principle of JC-LB Ringelmann flue gas blackness diagram: The Ringelmann smoke concentration map was proposed by Ringelmann in France at the end of the nineteenth century. This method is to place the graph in an appropriate position, compare the blackness of the graph with the blackness (or opacity) of the smoke, and evaluate it visually. There are many specifications of Ringelmann diagrams. What our company prints is a general standard format, which is composed of six small blocks with different blackness of 14cm×21cm. Except for the all white and all black blocks, the other four blocks are drawn with black bars of different
