The Paterson Triple Darkroom Timer features three independently controlled timing fields; countdown/count up timing, 24 hour clock, and stopwatch, accurate to .01 second. This makes it extremely useful when timing print or film development, hot mounting or laminating. Featuring a large LCD readout, three distinct audible signals ensure you won't miss your moment.

A magnetic back makes it easy to mount the timer where its needed. It runs on an AAA battery.
