ABSTRACT:
This invention generally relates to a reflection-photometric analytical system having a measuring head comprising a source of radiation and a radiation detector for the reflection-photometric analysis of a target surface of a test object arranged at a distance from the measuring head and in particular of a test strip for body fluids such as urine or blood. A triangulation unit operating on the basis of optical triangulation is proposed for contact free checking of the distance in order to monitor or regulate the measuring distance.
