Paterson 暗房放大機三聯計時器

The magnetic back is a lifesaver for keeping this timer securely attached to my enlarger stand. Each of the three independent timers has a distinct beep, so I never get confused about which one is for the print and which for the developer.

I’ve been using the three independent timing fields for different steps in my print development workflow, and the large LCD is clear even under dim safelights. The magnetic back lets me stick it right on my enlarger stand, which saves bench space.

The three distinct audible signals are perfect when I’m moving between print and film steps—I never lose track of which timer is going off. The large LCD is easy to read in the dim safelight, and the magnetic back keeps it stuck to the enlarger stand without any fuss.
