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.

    Model 300 Electro-Mechanical Darkroom Timer is rated 4.1 out of 5 by 15.
    Rated 4 out of 5 by from Just as I'd remembered Tired of all things digital, especially photo software, I decided to set up a small darkroom and break out my old OM1s, so ordered a whole kit from BH including the GraLab. I had other timer choices, but remembered the ease and comfort of the big timer's glow back in the days I processed and printed all over the world. Overall, I'm not disappointed, although this model has a lot more plastic than the older ones and is a little slicker in design which results in a beveled case which makes it sit with a slight downward tilt. On the positive side, it does exactly what I expected and appears to be very accurate and certainly easy and intuitive to use--great when you're really busy or new to darkroom work. On the negative, it has a real cheesy on/off switch with a little plastic splash cover that makes the switch difficult to operate. I can't see the reason for this as the other switches have no covers and the device is certainly not water resistant. Additionally I've had trouble with the too-loud alarm making a buzzing sound even when turned all the way down. Both problems were easy to fix.

    Rated 1 out of 5 by from Almost unusable due to buzzer Very disappointed with this purchase. Attention: the current model of this timer has no on-off switch or volume control for the buzzer. And it is blood-curdlingly loud. As expected, the safelight goes on and the enlarger goes off at the end of the timer cycle, but you'll need to turn off the power switch to shut off the buzzer so you'll be in the dark. In other words the safelight outlet is useless because the buzzer caqn't be controlled. I emailed gra lab tech support to see if there was a way to limit the buzzer duration or disable it altogether. I never heard back. A shame because I grew up with these timers and had a high regard for the company. I think the model recently changed which could be why other reviewers had a better experience.

    Rated 4 out of 5 by from Good Timer for the Darkroom I had used the GraLab timer for about 4 months before I found one that I liked better. I had no problem seeing the time in the dark and the cord fit into my enlarger fine. Also kept accurate time. It is a decent timer. The replacement I found was more aesthetically appealing to me.

    Rated 2 out of 5 by from This timer works, but feels very cheap. I'm not impressed. I remember the old metal timers, and this one certainly is not what I recall. This one is made from about $2 of plastic, plus a motor, power cord, and a couple of plug sockets. I'd guess they probably put about $15 of parts into this when making it. If you were expecting the same quality as in the past, you will be disappointed. Nothing about this is made of metal, and it screams cheap plastic. The case, the hands, the face plate - all inexpensive plastic. Although it works, the buzzer volume is absurdly loud. I'm going to have to find a way to make it quieter to actually use, or my wife is going to jump out of her skin every time it goes off. There is one screw holding the back on, with a large warning about not servicing any parts inside. The plastic face plate is riveted on, so you can't remove it. I had high hopes for this due to the price, but I believe they are simply making a killing off of the product margin. Knowing what I know now, I would not purchase this again and would use a cell phone instead.

    Rated 4 out of 5 by from Great Clock, LOUD buzzer I use this for my home-development setup. I love the clock - it takes me back to my old darkroom days. It's easy to setup and if I ever get around to setting up a full darkroom, I can use it there with no problem and route my enlarger through there. It can be floor or wall mounted, which is nice as well. It is primarily made of plastic, so it's not quite like the old chunky timers from years past - that can be a plus or a minus for a person. The one reason I gave it a 4 star rating is that the buzzer is LOUD. I mean wake the dead loud. I absolutely cannot use this in my house without alerting everyone in the house, asleep or not, to what I'm doing. There's no sound port that I can muffle, nor any way to turn the buzzer off, so it's still a great timer, but I may need to find alternate methods of timing when my son is taking a nap.

    Rated 4 out of 5 by from Sturdy and useful I bought this for use on stage at a theater in NYC rather than a darkroom, so it gets a lot of wear and tear, but is holding up very well so far. It features a nice readable display, an adjustable buzzer sound, and an outlet for plugging in a bulb to go off when the timer is done. It's easy to use, as well.

    Rated 4 out of 5 by from Works well but buzzer too loud Using with a UV light box for platinum/palladium printing. Model 300 has 3-prong outlet needed for my light box. Works as described. Buzzer cannot be turned off or turned down and is overly loud. Shipped quickly, well packed, instructions easy to follow.

    Rated 5 out of 5 by from Great for x-ray lab film processing This is a great darkroom timer for industrial x-ray film processing. High quality, easy to use & read, and durable. A must have for the lab. I've recommended it to several colleagues.
