The DURST PENTACOLOR darkroom
light
is equipped
with
five
inter-
changeable
filters:
the
first
for
white
light.
the
others
for
the
colours
orange. ruby-red. olive-green. and pan-green. The
filters
are mounted
in a
turntable
which
allows easy
setting
of
the
desired illumination.
A heat absorbing
filter
prevents bleaching
of
the
colour
filters.
By
tilting
the
housing.
indirect
illumination
may be obtained. The
light
is
either
fixed
to
the
wall
or
placed on the table.
The
electronic
exposure measuring and
timer
apparatus
DURST
TIM
100
is a compact table model
with
a shock-proof
plastic
housing. Its electron-
ic
construction
guarantees maximum measurement accuracy and
exposure
timing
so
that
exposure mistakes are absolutely impossible.
The
measurement
and
timing
circuits
are mains stabilized and com-
pensate
completely
for
current
oscillations
of
± 10%. The measuring
sensitiveness is
extremely
high even
with
weak
light.
it
corresponds
to
an
aperture value
of
±
1/4.
The exposure
time
range is
very
large and enables
25
different
focusings
from
1
to
250
seconds. The exposure
times
are
logarithmically
staged. 3 stages double
the
exposure
time.
The
unit
may be used
with
the
following
currents:
110V. 125V. 140V. 160V. 220V. and 240V (50 anrl
60
cycles).
Thanks
to
its
highest
precision
of
measurement
the
TIM
1().'
is also
well-suited
for
colour enlargements.
The
DURST STABI voltage stabilizer. available in
mod!s
for

and 2000W. is indispensable, especially
