Omega CT-40 Darkroom Timer/Controller

The CT-40 was conceived to be much more than a timer. In addition to being manually programmable, by using an expansion interface and optional probes, the unit could function as an exposure meter, electronic digital thermometer, and ph meter. For process timing, several different pre-programmed modules were available for specific processes such as C-41, E-6, and Cibachrome.
