Reliable and accurate 6--minute timer. Can be set in minutes for four-color developing and seconds for enlarger control.

Minutes and seconds can be easily read across the room in total darkness, making the Model 300 timer ideal for film processing, especially the precise timing required by color processing. The 60-minute timer range can be set in minutes for developing and seconds for enlarger control. Two hands permit quick setting by seconds, minutes or a combination of seconds and minutes. 

An exclusive dual-cam mechanism provides extreme accuracy for long time intervals: +/- 0.15% at maximum dial setting. Two separate outlet receptacles control an enlarger or printer and safelight by a combination of time/focus switch. 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.
