GraLab 300 Darkroom Timer

Even in total darkness you can read the minutes and seconds on GraLab's Model 300 Darkroom Timer. It is used in industrial/commercial photo labs, graphic arts, printing and hobbyist darkrooms and is probably the most popular darkroom timer of all time.

Set by seconds, minutes or a combination of the two, GraLab's exclusive dual-cam system gives you exact timing over long intervals.

Two, three-wire receptacles can control an enlarger or printer and safelight with a combination time/focus switch.

Rubber base pads, wall mounting keyholes and a recessed hand grip on the 7-1/2" x 7-1/2" x 2-1/2" polycarbonate case, gives you multiple placement choices.

  • Plastic boot over power switch prevents corrosion from chemicals or water
  • Buzzer automatically signals end of cycle (Volume controlled; Must be manually set)
  • Large 6.5" diameter face with easy-to-read glow in the dark numerals
  • Three wire grounded cord
  • Model 300 withstands high impact, resists chemicals and moisture, and is electrically nonconductive.
