A Direct-Reading Photoelectric Densitometer
A direct-reading 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 a reproducibility of approximately ∓0.00.5. A motor-driven circular neutral wedge is used as the balancing means and the density scale marked on the wedge is read by a stroboscopic flashing light.
