Abstract
The sensor (1) comprises a sensor body (3) thermostatable by means of a first thermostating system (14,15) and having an outer surface (3a,40a) for application to the human body (28) in heat conductive relationship therewith, said outer surface (3a,40a) forming the measuring surface of the sensor (1). The sensor (1) further comprises analyte sensing means (7,8) arranged in said sensor body (3) and being thermostated through said body (3) by means of the first thermostating system (14,15). The sensor (1) further comprises means (16,41) arranged in the sensor body (3) in heat insulated relationship therewith while in heat conductive relationship with a delimited surface part of the sensor measuring surface (3a,40a). The means (16,41) is thermostatable by means of a second thermostating system. The delimited surface part is located within the outer periphery of the sensor measuring surface (3a,40a).
