Abstract
The invention concerns a differential-reflectance photometer for quantitatively evaluating test strips, especially for chemical analysis. The differential-reflectance photometer is characterized in that two optical channels are arranged in one housing in V-shaped fashion with each channel receiving an optical emitting and an optical receiving arrangement, that the channels enter a common space at the apex of the V, that a reference field associated with both emitting and receiving arrangement is provided on the bottom of the common space, that the emitting and receiving arrangements are connected to a common evaluation apparatus, and in that between the reference field and the emitting and receiving arrangements is a receiving slot, which intersects both channels, for receiving a test strip with two test fields each of which becomes associated with a respective one of the two channels.
