General Information
1.1 Introduction
The Model 07-440 Digital Densitometer is designed to measure optical density with high accuracy and
reliability. With minimum training, an operator can make the precise, repeatable measurements necessary
for accurate photographic film exposure and processing control. At the push of a button, the result of each
measurement is transmitted via an RS-232 interface which allows the operator to acquire this data on a
computer system.
Solid state dependability together with rugged construction make the instrument exceptionally stable over
long periods. Due to the dependability and construction of the instrument, maintenance requirements are
minimal.
