Gralab Gralab 300 Darkroom Timer

Even in total darkness you can read the minutes and seconds on Gralab's Model 300 Darkroom Timer.

The Model 300 gives you the accuracy you need for sensitive color processing or x-rays. Also used in industrial/commercial photo labs, graphic arts, printing, hobbyist darkrooms.

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

Controls other equipment. Two, three-wire receptacles control an enlarger or printer and safelight with a combination time/focus switch. Rated at 600w each, the outlets can be used for operating most darkroom equipment. Model 300 can also be used with a relay for heavier loads.

Large numerals on a 6 1/2" luminous face are easy to read. Volume control adjusts the buzzer alarm for your situation.

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/PET case give you the multiple placement choices. Model 300 withstands high impact, resists chemicals and moisture, and is electrically nonconductive.
