Even in total darkness, you can read the minutes and seconds on GraLab's Model 300 Darkroom Timer (210-250VAC, European Voltage). It is used in industrial/commercial photo labs, graphic arts, printing, and hobbyist darkrooms; 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 7.50 x 7.5 x 2.5" polycarbonate case give you multiple placement options.
Note! This item is wired for 210-250VAC, European Voltage ONLY
