More Information
Summary:A method is disclosed for calibrating transducers for determining gas concentrations, in particular for the transcutaneous measurement of blood gases. In the method, the testing chamber is exposed on its measuring surface, through an overlay, to a known gas concentration. The method provides for a simpler application of the calibration medium to the measuring surface of the transducer, such that an overlay provided with substances required for furnishing the known gas concentration is applied directly onto the measuring surface of the testing chamber, covering it. An overlay is also disclosed and is embodied as a paper strip having two impregnated zones, separated from one another by an intermediate piece provided with a coating.
