Abstract
An attenuated total reflection ('ATR') sensor () determines a substance dissolved in a measurement medium (). A method is taught to verify a calibration and/or to perform an in-line calibration of the sensor. The ATR sensor includes a housing () and an ATR body (). A light source () and a detector () are arranged in the housing. The ATR body has at least one measurement surface () and, arranged parallel to the latter, a calibration surface (). The measurement surface () can be brought into contact with the measurement medium. A calibration chamber (), arranged in the housing, is delimited on at least one side by the calibration surface.
