The GraLab Darkroom Timers are without a doubt the most popular darkroom timers of all time and used in darkrooms all over the world. The timer is of American manufacture and has become very difficult to obtain in Europe today. The last model that is being made, Model 300, no longer comes with an European plug. As a result the delivered timer comes with an American plug but we provide a free conversion piece so that the timer can be used immediately.

The Model 300 timer offers a 60-minute time range that 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. Minutes and seconds can easily be read across the room in total darkness, making the Model 300 timer ideal for film and paper processing, especially the precise timing required by color processing. 

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. Please note that these outlets are also adapted to use of an American plug but an additional conversion piece can solve this. 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 of durable plastic and measures about 19 x 19 x 6,34 cm. 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.
