GraLab 300 Overview

Even in total darkness you can read the minutes and seconds on GraLab's Model 300 Darkroom Timer. It is used in industrial/commercial photo labs, graphic arts, printing, hobbyist darkrooms and is probably the most popular darkroom timer of all time.

Set by seconds, minutes or a combination of the two, GraLab's exclusive dual-cam system gives you exact timing over long intervals.

Two, three-wire receptacles can control an enlarger or printer and safelight with a combination time/focus switch.

Rubber base pads, wall mounting keyholes and a recessed hand grip on the 7-1/2" x 7-1/2" x 2-1/2" polycarbonate case give you multiple placement choices.

Plastic boot over power switch prevents corrosion from chemicals or water
Buzzer automatically signals end of cycle
Large 6.5" diameter face with easy-to-read glow in the dark numerals
Three wire grounded cord
Model 300 withstands high impact, resists chemicals and moisture, and is electrically nonconductive.

That is exaclty right. the safelight is on and the enlarger turns on and off when the timer is going or you can turn the enlarger on to focus by using the focus switch at the top of the timer.
