Varian 938-41 Turbo Leak Detector – Mass Spectrometer, 115V

Product Description

Varian 938-41 Turbo Mass Spectrometer Leak Detector – High-Sensitivity Helium Leak Detection System

This used Varian 938-41 is a high-performance helium mass spectrometer leak detector (MSLD) designed for precise leak detection in vacuum systems, aerospace components, and industrial applications. The 938-41 is a well-documented workhorse, with models used at NASA and other government agencies for critical leak testing .

This unit features a turbo pump for clean, high-speed vacuum generation, offering a sensitivity of 2 x 10⁻¹⁰ atm cc/sec for helium at the test port . The high sensitivity and robust design make it suitable for identifying minute leaks in sealed payloads, pressure vessels, and vacuum chambers . It is capable of detecting leaks at a rate of 10−910−9 cc/sec or better, a standard often required in aerospace and nuclear applications .
