ZF-20DI dimming digital display darkroom timer adopts single chip microcomputer technology, with red light brightness adjustable, simple and compact circuit, accurate timing and "clock/timing" functions. It does not affect the timing of the clock in the timing state. It uses a unique light-emitting button, even if you are in a dark room where you can't see your fingers, you can clearly see the red "start" button without any other light sources, and the operation is extremely convenient. It can be arbitrarily placed on the table or hung on the wall. It is an indispensable tool for darkroom workers.
