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 and smaller leaks. Leak Type A is intended for accumulation testing only.

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

Types and Leak Rates

Sintered stainless steel leaks (Type A, B and C)
Target flow between 5×10^-2 and 5×10^-4  (5%H₂/95%N₂)

Quartz capillary leaks
Target flow 5.2×10^-5 (5%H₂/95%N₂) equal to 10g/y R134a
