Opacity readings
WebOpacity meters read between 0.00016 and 0.00024 m-1per ppm NO2, depending on the sensor bandwidth [853]. A 300 ppm NO2concentration in a diesel engine—not an unrealistic assumption—would cause a 0.06 m-1opacity reading, which is equivalent to 40% of the Euro III EEV pass level, intended to be for soot emissions. WebThe reading can be used as a reference value while other readings can be recorded as a sample and later be compared to the reference value easily to determine delta pass/fail. 58 mm sphere with wavelength from 400 to ... - …
