Precision Timing for Darkroom and Kitchen

The GraLab Model 255 is a large-dial electromechanical timer built for consistent results in photographic processing and culinary tasks. Its robust construction handles demanding laboratory and food-service environments. The intuitive interface allows quick operation so users can focus on the process rather than the tool.

Replaces Basic Countdown Timers

Upgrade when inconsistent results from simple digital or mechanical timers affect print development or recipe timing. The jump is worth it when repeatable, precise intervals are critical for colour work, B&W processing, or professional kitchen workflows. Buyers who need programmable multi-step sequences or digital data logging will not find those functions here.

Simple Plug-In Installation

Connect the unit to a compatible mains outlet and link it to the enlarger or appliance circuit; no software or drivers are required. The large dial and clear markings reduce setting errors under safelight conditions. Ensure the load rating matches the connected equipment to avoid tripping the timer's internal protection.
