07-424 Digital Densitometer

The Digital Densitometer is an easy to use precision instrument that quickly measures the optical density of film.

Constructed of rugged steel and compact enough to fit on any crowded worktable, it offers exceptional accuracy (± 0.02 optical density). The optical density value is displayed in bright LED numerals on the detector arm. The sample table is 6.125 inch x 10.50 inch with a 4.75 inch x 5.50 inch illuminated section. It will accommodate film up to 14 inch x 17 inch and provides ample room for positioning any selected area under the detector.

The detector is a hermetically-sealed silicon photodiode. The detector lamp is at full brilliancy only during the actual measurement, thus preventing heating problems and ensuring very long lamp life with minimum wavelength shift or other degradation. When necessary, the lamps are easily replaced. The densitometer includes a five-step optical density tablet.
