Densitometer - Wikipedia
A densitometer is a device that measures the degree of darkness (the optical density) of a photographic or semitransparent material or of a reflecting surface. [1] The densitometer is basically a light source aimed at a photoelectric cell . [ 2 ]

densitometer, device that measures the density, or the degree of darkening, of a photographic film or plate by recording photometrically its transparency (fraction of incident light transmitted). In visual methods, two beams of equal intensity are used.

The density of a solution can be measured manually or digitally. For more detailed information on how to measure density with pycnometers, hydrometers and digital density meters please see our 3 Ways to Measure Density guide.. Manual methods like pycnometers and hydrometers are widely used for the determination of density and related values, e.g. specific gravity, alcohol%, BRIX°, API degrees ...
Densitometers Selection Guide: Types, Features, Applications
A transmission densitometer is used to measure the optical density of transparent materials. Densitometers measure the value of light absorption in photographic films or printed paper. They are specified for either black and white or color film applications.

Densitometry - Wikipedia
According to the principle of operation of the densitometer, one can have: spot densitometry: the value of light absorption is measured at a single spot; line densitometry: the values of successive spots along a dimension are expressed as a graph

Densitometer Definition, Function and Calibration Importance
What is a densitometer? A densitometer is used to accurately measure the photographic (optical) density at any spot on a radiographic film. For most types of densitometers the size of the measured area is approx. 1 mm2 .
