General Information
1.1 Product Description
The Model 07-443 Densitometer is designed to measure transmission density per ANSI specification
PH2.19-1986. The unit’s high accuracy and reliability allow precise and repeatable measurement to be
made quickly and easily with very little operator training. In addition, due to its solid-state design and
rugged construction, the Model 07-443 requires a minimum amount of maintenance. By using the 07-443
Densitometer, readings of optical density for film media can be obtained directly, accurately, and
reproducibly.
The 07-443 Densitometer features a rugged aluminum bottom casting, which houses four (4) AA batteries
and the detector light source. The top section of the Densitometer holds the 3 1/2 digit display, ON/OFF
push-button, and the READ, LAMP, and ZERO push-buttons. Refer to Figure 1-1 for a general view.
A 1 mm aperture is included as an accessory with the instrument. When changing apertures, the
instrument must be readjusted to zero by using the zero adjustment potentiometer located on the side of
the instrument.
