Product description

The GRALAB GR300S 60-Minute Darkroom Timer is ideal for film processing, especially the precise timing required during color processing. This reliable and accurate 60-minute timer can be set in minutes for 4-color developing and seconds for enlarger control. The 2 hands permit quick setting by seconds, minutes, or combinations of seconds and minutes.

A suitable dual-cam mechanism provides good accuracy for long time intervals: ±0.015% at maximum dial setting.

It can be used with a relay for heavier loads.
