Minutes and
seconds can easily be read across the room in total darkness, making
the 300 ideal for film processing, especially the precise timing
required by color processing. The 60-minute time range can be set
in minutes for developing and seconds for enlarger control. Two
hands permit quick setting by seconds, minutes or combinations of
seconds and minutes.
An exclusive
dual-cam mechanism provides extreme accuracy for long time intervals:
+/-015% at maximum dial setting. Two separate outlet receptacles
control an enlarger or printer and safelight by a combination time/focus
switch. Each outlet has a 600 watts rated capacity for operating
most film processing equipment. The Model 300 can be used with a
relay for heavier loads.
The case is
made from a blend of hybrid plastics and measures 7 1/2" x
7 1/2" x 2 1/2". It is exceptionally strong, withstands
high impact, resists chemicals and moisture, and is electrically
non-conductive. The case has a recessed handle in the back and keyholes
for wall mounting. |
