Product description

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, 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.

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 give you multiple placement choices.

    What is a more reliable power switch for the Graylab 300? I've had 2 of the cheap rocker switchers fail/. I'm capable of doing the replacement.
