Abstract

A device for optically evaluating test strips includes a housing carrying the measuring optics and a test strip holder insertable into and removable from the housing by sliding into and out of a receiving compartment of the housing, with the test strip holder containing all of the surfaces with which the significant portions of test strips come into contact, thereby permitting those surfaces to be easily cleaned upon removal of the test strip holder from the housing. The device also assures proper positioning of an easily inserted test strip, allows for heating of the test field to a fixed temperature, and allows for both empty and dark field calibration of the optical system.
