These are excellent value for money basic mechanically actuated enlarging timers.Two timing ranges are covered, 0.1 to 6 secs. and 1 to 60 seconds, with switching to change between the two. The selected time is set using a dial with central knob. A 'focus' button switches the light source on for focussing. The timer automatically resets to the same selected time at the completion of exposure. The repeat accuracy of these timers is particularly good.
