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.
本文报告了对一种基于转子流量计原理的市售麻醉蒸发器测试设备（即“Tekatest”）可靠性的调查结果。在原型设备中，发现Tekatest获得的结果与气相色谱法和质谱法得出的结果之间存在高达27%的离散差异；在一个有所改进的版本中，约24%的单向误差变得明显。因此，到目前为止，这种测试设备不推荐用于临床使用的蒸发器的重新校准。
