MS-40GT PORTABLE HELIUM LEAK DETECTOR PORTABLE DRY/WET HELIUM LEAK DETECTOR 便携式氦检漏仪 便携式干/湿氦检漏仪
The MS-40GT available either wet or dry pumping package is fully automatic, easy to use, and highly accurate. These advanced leak detectors are ideal for a broad range of applications including clean, oil-free testing.
Helium that is present in a test object is drawn into the unit (either through the test port or through the sniffer valve), isolated and detected by a mass spectrometer, and converted into an electric signal. The electric signal generated is proportional to the leak rate of the helium drawn through the leak found in the test object. Once this signal is amplified, the signal is displayed as a leak rate on the User Panel of the MS-40GT.
It also meets the stringent requirements for robustness, reliability and ease of maintenance that are essential in any industrial environment..
MS-40GT可湿抽或干抽，全自动，使用方便，精度高。这些先进的泄漏检测器非常适合广泛的应用，包括清洁、无油测试。
测试对象中存在的氦气被吸入装置（通过测试端口或嗅探阀），通过质谱仪进行分离和检测，并转换为电信号。产生的电信号与通过测试对象中发现的泄漏抽取的氦气的泄漏率成比例。一旦该信号被放大，该信号就会在MS-40GT的用户面板上显示为泄漏率。
它还满足在任何工业环境中都至关重要的坚固性、可靠性和易于维护的严格要求
