Digital densitometer FMD-12

Characteristics
Digital densitometer FMD-12 is a portable battery-powered
densitometer designed for measuring radiograph blackening
using an external light source. It has been developed for
bulb negatoscopes (it can also be used on negatoscopes
with fluorescent and LED light, we recommend recalibration
of the instrument using a densitometric etalon, e.g.
FOMASTEP E-09).
Technical Description
Densitometer FMD-12 consists of the actual measuring
instrument, the measuring probe, and the connecting
shielded cable. The connector for connecting the probe
using the shielded cable is located on the face of the
instrument under the display and protected against
spontaneous disconnecting. The measuring probe is of a
pencil design with a plastic black case and it is connected to
the instrument using a short cable and it is removable.
Densitometer FMD-12 is equipped with semi-automatic zero
setting and automatic turning off, when the instrument is not
used.
Instrument Recalibration
Densitometer FMD-12 allows for recalibration according to
ASME SE–1079 or ASTM E 1079–85 (“Standard practice
for calibration of Transmission densitometers") using the
setting element located on the upper right side of the
instrument. The recommended interval for repeated linearity
checking or instrument recalibration is 90 days. For
instrument recalibration, we recommend using FOMASTEP
E-09 densitometric etalons.
