Abstract:
1. A handheld colour measurement device with a housing in which an opto-electronic measurement unit is located which receives measurement light originating from a measurement object and converts it into corresponding electric measurement signals and processes the measurement signals into digital measurement data characterizing the colour of the measurement object, and having passive components required for the realization of different application functions, which components can be selectively moved into the measurement beam path, wherein the passive components are positioned in a first housing block, that the opto-electronic measurement unit is located in a second housing block, and that the second housing block is adjustable relative to the first housing block to several, defined application positions in which application positions one of the passive components is respectively located in the measurement beam path of the opto-electronic measurement unit, wherein the second housing block is rotatably adjustably positioned in the first housing block, and wherein the first housing block is externally at least of annular shape and that the second housing block externally is at least of drum shape and is positioned in the interior of the first housing block for rotational adjustment about its axis.
