Instruction Manual Comparator 100
The JOBO Comparator is an electronic measu-
ring instrument for the determination of expo-
sure times for B/W and color enlargements. It is
suited for the following applications:
– Determination of exposure time for all B/W
enlargements
– Determination of exposure time for color
enlargements of slides and negatives
The operation is simplified by the use of LED’s
to guide you to the proper exposure time.
