Abstract
A direct-rending photoelectric densitometer has been built which shows the density of the area being measured at a reading window. A density range front 0 to 3.0 is covered with n reproducibility of approximately ∓0.00.5. A motordriven circular neulral wedge is used as the balancing means and the density scale marked on the wedge is rend by n stroboscopic flashing light.
