Flow limiter for QD connection

The connection to an inflation hose allows you to measure gas mixtures in already filled cylinders without the need to remove the second-stage regulators. Simply disconnect an inflator or another quick-release connector, which will deliver a flow of 0.2 l/min at 10 bar. The connector is cylindrical with a diameter of 5.8 mm and is connected to the He/O2 analyzer via a connecting tube.
