How do I use a Sensorcon with a Scuba tank?

FYI, Plastic parts should only be able to be pressed up against the valve opening. Anything attached can turn into a missile if the valve is opened too much.

I could be wrong, but it looks like the yoke connector might be a yoke to DIN adapter, and the black part is plastic with a brass nipple that slides in for the threaded end. I have no doubt the plastic screw in part could be made with a 3D printer and you could easily find a nipple to insert. Using minimal air flow from the tank, you would not need anything that requires high pressure tolerances. Even if the threaded part leaked a bit, the Sensorcon would read the CO in the air coming into the sensor port whether you stuck the hose in the port or put the Sensorcon in a plastic bag with the hose inserted into the bag.

I don't own a 3D printer but I could probably get a piece of PVC pipe that is the same diameter and have my plumber thread it to match the Yoke adapter. Then I can cut it to the right length and glue on a thick flat piece of PVC and shape it up with my Dremel tool.
The nipple would be pretty easy to insert after that.
