With high visibility and outstanding accuracy, the GraLab Model 300 Electro-Mechanical 60-minute timer is ideal for film processing and general darkroom photography applications.

High Reliability and Accuracy

Featuring a dual-cam mechanism, the electro-mechanical timer uses an electric synchronous motor that provides an accuracy of +/-0.015% at the maximum dial setting. The high accuracy makes the Model 300 ideal for any colour processing that requires precision timing.

Dual Control Outlets

Equipped with two 600W power outlets, the GraLab 300 is suitable for operating most film processing equipment. The two outlets ensure automatic switching between an enlarger or printer and a safelight through a combination time/focus switch. For heavier electricity loads, the timer can be used with a relay.

Precise Timer Setting

With two hands, the 60 minute time range can be set by minutes for film processing, or seconds for enlarger control, or a combination of minutes and seconds.

High Visibility

A 16.5cm diameter face with large and easy-to-read numerals ensures easy visibility from a distance. The white luminous numerals and hands glow on the black dial, further enhancing visibility in darkrooms.

Chemicals and Impact Resistant

Specifically made for use in photo labs and darkrooms, the Model 300 Timer is designed to resist the effect chemicals, moisture and impact. The case is made of electrically non-conductive plastic to protect against electrical shocks. The strong and durable case features rubber base pads to withstand vibrations, while a plastic boot over the power switch prevents corrosion from chemicals and water. A textured non-slip finish and a recessed handle ensure it can be relocated with ease.
