Diesel smoke testing for heavy fleet

Posted on November 15, 2021


In the photo, Garage technician James Arieta is performing the annual diesel smoke opacity test using our newly purchased wireless opacity meter. The smoke opacity meter is an instrument that measures the optical properties of the diesel exhaust. In California, the periodic smoke inspection program requires the owner of California-based heavy truck fleets to perform annual diesel smoke opacity of their vehicles. This test is important to make sure the exhaust and emission systems on heavy trucks is properly maintained.
