氦质谱检漏仪是质谱仪的一种特殊形式。在检漏技术中,它是近代最迅速、最灵敏、最可靠地检查真空系统、真空器件和一切气密性设备密封性能完善程度的一种专用仪器,在真空技术和有关工业中获得广泛的应用。我厂从1963年开始生产JLH-1型氦质谱检漏仪以来,经过不断改进,该仪器性能稳定、可靠,实际灵敏度优于5×10~(10)托·升/秒,反应时间小于3秒,是目前国内使用较为普遍
Helium mass spectrometer leak detector is a special form of mass spectrometer. In the leak detection technology, it is the most modern, most sensitive and most reliable inspection of vacuum systems, vacuum devices and all air tightness of the sealing performance of a special instrument, in the vacuum technology and related industries to obtain a wide range of application. Since 1963, our factory has been producing JLH-1 Helium Mass Spectrometer Leak Detector. Since its continuous improvement, the instrument has stable and reliable performance, the actual sensitivity is better than 5 × 10 ~ (10) Torr · L / s and the reaction time is less than 3 Sec, is currently more common use of domestic
