General Information
1.1 Product Description
Model 07-417 (Figure 1-1) is a portable, battery or line operated Sensitometer designed to make
reproducible exposures on x-ray film for measuring the performance of film processing systems. Dual
color capability makes this unit ideal for use in blue sensitive sheet film and green sensitive sheet films as
well as Cine film applications.
In quality control applications, the Sensitometer can be used to expose a sheet of x-ray film under
optimum conditions. Other films can then be exposed periodically (e.g., daily) and compared to the initial
film using a densitometer (e.g., Model 07-445). It can then be determined if there is a need for corrective
action in order to obtain high quality radiographs.
