Helium Leak Standards

LACO manufactures a wide range of Helium Leak Standards using our proprietary micro tube capillary design. We are so confident in the reliability of this design we offer a limited lifetime warranty. These leak standards are available in both reservoir and open-style configurations. For leak rates in the 10^-9 range and lower, select a permeation style helium leak standard with reservoir. Our Helium Leak Standards are used in a variety of applications including calibrating helium mass spectrometer leak detectors and helium leak test systems. Open-style helium leak standards can be built into customer test parts. For calibrating helium sniffer probe leak detectors see our Sniffer Leak Standards. We also offer OEM replacement leak standards for many models of helium mass spectrometer leak detectors, including LACO’s TITAN VERSA helium leak detector.

All our leak standards are calibrated in our ISO 17025 accredited calibration lab.
