Abstract
This paper introduces the construction, work process and operating principle of the Model J-90 DieselExhaust Transient Smokemeter. To improve the accuracy of measurement, a new efflux system is used to pro-tect the photoelectric element from pollution. The experimental results show that this smokemeter has wide use and high accuracy. Its construction is simple and compact with lower cost.
