120 V AC 60-minute interval timer

The GraLab 254 is a 120 V AC timer that runs for up to 60 minutes in 1-minute steps. It delivers ±0.015 % accuracy at the maximum setting, making it reliable for darkroom processing and food-service timing. A constant-tone buzzer sounds automatically when the interval ends.

Photographers and commercial kitchens.

Photographers who need repeatable enlarger or developing cycles and busy kitchens that require an audible alert over background noise will find the 600 W lamp and 1 200 W resistive capacity useful. The 1-minute increment prevents use for processes that demand second-level precision or intervals shorter than one minute.

±0.015 % accuracy at 60 minutes

The single specification that decides suitability is the ±0.015 % timing accuracy at the full 60-minute range. This precision supports consistent darkroom exposures and repeatable cooking cycles, while the 1/3 HP motor rating covers compatible ventilation or mixer loads.
