No, the simplest is to leave the chopsticks at the Chinese restaurant and just leave the analyzer plugged in to the inflator hose after you shut off the tank valve.Yoke or DIN?
You can certainly use a first stage that has a SPG and a LPI hose...then plug the analyzer into the LPI hose with a flow restrictor in it. Be sure and have a way to purge the system so you can get the reg off the tank. The simplest is to use a chopstick to press the Schrader valve in the LPI hose after the analyzer is removed.
