This kit provides a way for you to test your existing built-in O2 system to determine if it's compatible with our AVI 1 and 2 place standalone systems.  

Simply test by connecting the provided plumbing to your cannula port to observe the pressure in-line using the convenient gauge and valve.

Ideal pressure should be 40-60 PSI when the valve is in the off position without flow. 

Price includes shipping both directions for continental U.S. addresses.  Return the kit to us for a $75 refund. Enter discount code: TESTKIT.
