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.
