摘要： A leak detector having a pre-vacuum feed pump, a gas detector and a flow sensor. The detector also includes a buffer volume and a restrictor to be arranged between the feed pump and the flow sensor. This protects the flow sensor against pressure surges generated by the feed pump.

摘要： Usually, a sniffing leak detector must be calibrated for each tracing gas. The calibration comprises ranging of the spectral positions into the mass spectrum and the amplitude height. At least one mass line is determined with a calibrating gas. The mass lines lying between two mass lines and/or between a zero point and a line are determined by interpolation and/or extrapolation. In this manner, a sniffing leak detector can be used for such tracing gases which have not previously been used for calibration purposes.
摘要翻译： 通常，每个跟踪气体必须校准一个嗅探检漏仪。 校准包括光谱位置到质谱和振幅高度的范围。 用校准气体确定至少一条质量线。 位于两条质量线之间和/或零点与一条线之间的质量线通过内插和/或外推来确定。 以这种方式，嗅探检测器可用于以前未用于校准目的的追踪气体。
