The GraLab Model 300 is the classic general purpose darkroom timer, a staple in darkrooms for decades. This is the later version GraLab 300 with plastic case and hands, grounded outlets, volume control, and rocker switches for the On/Off and Time/Focus controls.
These timers are used, but in excellent condition. Each timer has been individually refurbished and tested to ensure that it is working to factory specifications. The timers are supplied with a copy of the original instructions, and we provide a 6-month warranty.
