Use this with your Palm Analyzer to allow you to check your tank mix with your BC inflator hose. No regulator removal is required because the flow adapter delivers 2-lpm constant flow using the quick release fitting on BC inflator hose. This adapter provides a precise flow rate to your Palm analyzer and fits both the Palm D oxygen analyzer and the Palm CO carbon monoxide analyzer. The constant 2 lpm flow rate provides a significantly more accurate and repeatable gas analysis result.

The BC connector on the end does not look like a normal quick connect post, but however this is not a defect in device. If you inspect the side of the end, near the metal tip, you will see a very (very) tiny round hole that has been drilled to provide a 2 liter-per-minute flow restriction on an inflator connection normally capable of 250+ liters-per-minute.
