The GraLab Model 171 Universal Darkroom Timer is a solid, reliable 60-minute timer for general darkroom work. It provides precise timing for enlarging, washing, and other darkroom functions. The receptacles give you the opportunity to run two appliances and switch between them effortlessly. A switch runs one item while the alternate receptacle will stop the other item's cycle at "zero".
