Abstract
The invention relates to a measurement instrument and a method for measuring the degree of covering of dust and dirt on a surface (30), for example in order to monitor cleaning quality, comprising a holder (2) by means of which a measurement object in the form of a test film (3) is held, during measurement, in a plane in a measurement zone (4) defined by the measurement instrument, the said test film (3) being coated with an adhesive layer (5) which, during testing on the surface (30), is intended to pick up any dust and dirt particles (31) from the said surface, the measurement instrument being distinguished in particular by: a light source (6) intended to illuminate the adhesive layer (5) of the test film (3) with obliquely incident light; a photodetector (8) intended to register the light intensity of the light reflected from the test film (3); and a processor (14) intended to compare the light intensity registered by the photodetector (8) with a predetermined calibration value, and to present a measurement value based on the said comparison, which measurement value represents the degree of covering of dust and dirt on the surface (30).
