To be able to correctly accept/reject test objects you need to measure to a set standard. You also need to calibrate your leak detector against a reliable reference leak. INFICON reference leaks for Sensistor industrial hydrogen leak detectors cover a wide range of leak rates to suit your specific application and include bigger leaks (Types A-C) and smaller leaks (Types E and G). Leak Type A is intended for accumulation testing only.

All leaks are traceable to NIST, NMIJ, NPL, PTB, etc., through the Mutual Recognition Arrangement of the BIPM.


Types and Connections

A, B and C
Sintered stainless steel leaks
Target flow between 5x10-2 and 5x10-4 (Air)
E and G
Crimped metal capillary leaks
Target flow between 7x10-5 and 2x10-5 (5%H2/95%N2)


  • Suitable for industrial applications
  • Easy to use
  • Available in different leak rates
  • Traceable to NIST, NMIJ, NPL, PTB, etc.

Typical Applications

  • Test and Calibration of Sensistor Industrial Hydrogen Leak Detectors
