Get all the benefits of state-of the-art
features in a compact, hand-held unit. Become a “speed reader” with
this accurate, rugged portable Clamshell Densitometer. It has today’s
most-wanted features for “go-anywhere” quality control testing...from
darkroom to darkroom, and from lab to field.
Features a self-contained light source
Fast and accurate results
Lightweight and portable
Reads grayscale up to 4.00 OD
Applications It’s easy to use. Just lift the “shell”
and insert the test film; close the “shell” and press the READ button.
The measured optical density appears on the three-digit liquid crystal
display. The self-contained light source makes it convenient to
use...anywhere. A carrying/storage case and a calibrated five-step
density tablet are included.
Introduction This compact, precision instrument is
ideal for maintaining consistent, high quality film processing. By
evaluating control films on a daily basis, the technologist can
identify processor variations before they affect clinical radiographs.
Also, processing conditions in multiprocessor departments may be
standardized. In the past, this was difficult in departments using
varied film-screen combinations in different areas. With this
sensitometer, proper exposure of either blue- or green sensitive x-ray
film is easily accomplished, with no need for internal adjustments. The
Hand-Held Dual-Color Sensitometer features a 21-step density wedge with
0.15 OD increments. The 21density gradient steps are numbered for
convenience. An innovative, dual-color, electroluminescent light source
provides precisely controlled repeatable exposures. The desired color
is selected with a front panel switch.
Applications To make an exposure, the platen is
raised and a sheet of film is inserted beneath it until the film stops
are reached. The platen is lowered and the exposure switch is
depressed. An audible buzzer is activated during the exposure. To
prevent double exposures, a two-second delay is engaged before the next
exposure can be made. When battery replacement becomes necessary, the
unit will not expose film. Battery life is approximately 10,000
exposures. Processor variations are monitored by comparing the control
film to previously processed films. Speed, contrast, and base-plus-fog
values can be graphically plotted for easier comparison.
