This equipment measures the quantity of light absorption produced by exhaust gases. The analyzer includes a chamber through which flow the exhaust gases. At the ends are connected an emitter and a light sensor, which measures the received luminous intensity. Because the light is projected through a specific wave length in the smoke to be measured, the incidental proportion reached by the receptor is used to obtain the darkening properties of the element and, in this way, determine If the gases are in a proportion to contaminate the environment.
