title: [Functional evaluation of "tekatest", a test equipment for halothane-vaporizers (author's transl)].
abstract: The results of investigations on the reliability of a commericially available test equipment for anaesthetic vaporizers based on the Rotameter principle (s.c. "Tekatest") are reported. In prototype devices scattered differences up to 27% between the results obtained by the Tekatest and those derived from gas chromatography and mass-spectrometry were noted; in a somewhat improved version an unidirectional error of about 24% became evident. Up to now, therefore, this test equipment cannot be recommended for recalibration of vaporizers in clinical use.
