Calibrated 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.

LIFETIME WARRANTY

  • Every calibrated leak standard produced by LACO is warranted to be free from defects over the lifetime of the standard. (Pressure gauges are warranted for one year).
  • All our leak standards are calibrated in our ISO 17025 accredited calibration lab.

MICRO TUBE CAPILLARY LEAK ELEMENT

Our Micro Tube Capillary is superior to traditional leak element technology (i.e. Teflon® Permeation, Crimped Metal Capillary, Glass Permeation, and Ceramic Permeation). This Helium leak standards are more reliable and rugged, with the capability of producing quick repeatable results.
