ABSTRACT:
A display device for the displaying of two measured values on a graduated dial 1 which has two scales 4 and 5 arranged concentrically to each other. Two pointers 6 and 7 are turnable around pointer shafts 8 and 9 which are coaxial to each other and each of which is associated with a separate scale 5 and 6, each pointer 6 and 7 being adapted to be driven in rotation by separate measurement mechanisms 13 and 14 respectively. The measurement mechanisms 13 and 14 are arranged coaxially to each other on opposite sides of the graduated dial 1 and the ends of the pointer shafts which carry the pointers 6 and 7 face each other.
