FSLT – Fixed Sniffer Leak Teflon


We developed the FSLT Helium Leak Standards specifically for calibrating sniffer leak detectors and avoiding clogging problems common to calibrators with a capillary leak element. This is particularly important for small leak rates and leaks used in industrial plants.

The FSLT Accu-Flow™ calibrated leaks are available for any specific leak rate within the usual range for “Sniffing” of E-4 to E-6atm-cc/sec. They can be used with all makes of leak detectors.

  • Never clogs: permeation element eliminates threat of clogging
  • Versatile: specify an exact leak-rate at your test point
  • Simple: requires minimal user training
  • Accurate: no dead spaces or false readings
  • Reliable: easy probe positioning allows for repeatable results
  • Meets ISO requirements: NIST-traceable, A2LA-accredited Calibration Certification
