I did a search on this and found it in a UK website:

and it's about 74 English pounds. Ouch! It could be double that in U.S. dollars. For that price I'll use a sticky type or the inline gauge for way less money.

Here's another link:

and it describes this device cannot be used for refillable cylinders. WHAT?! That alone makes it unsuitable for our purposes however I think they meant to say, "not intended for non-refillable cylinders since their diagram shows a refillable cylinder.
