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)
 

Advantages

• 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
