Abstract

A handheld colour measurement device includes a housing in which an optoelectronic measurement unit is located which receives measurement light originating from a measurement object, converts it into corresponding electrical measurement signals and processes these measurement signals into preferably digital measurement data characterizing the colour of the measurement object. It further includes passive components required for the realization of different application functions, such as measurement windows and reference standards, which can be selectively positioned into the measurement beam path of the measurement unit. The passive components are positioned in a first housing block (100) and the opto-electronic measurement unit as a whole in a second housing block (200). The second housing block is adjustable into several defined application positions relative to the first housing block, in which application positions respectively one of the passive components is located in the measurement beam path of the opto-electronic measurement unit. This special division into two mutually relatively adjustable housing blocks allows an easy realization of a compact colour measurement device suitable for many application functions, which is distinguished by a particular user friendliness.

Claims

12-1. The handheld colour measurement device according to claim 1, wherein one ambient light measurement window is located at the upper surface of the first housing block and is preferably provided with a scattering disk.

25-2. The handheld colour measurement device according to claim 1, wherein it is equipped with a preferably screw-on tripod holder.
