A chamber to control concentration of a vapor: Is there a name for this equipment?

Mechanical engineer here so please excuse me if my question seems dumb to you!


I want to have a chamber $(\approx 40 \times 30 \times \pu{30 cm})$ to control concentration $(\pu{ppm})$ of a flammable material (e.g. alcohols or ketones) at a specific temperature $(T\approx \pu{24 \pm 10 ^\circ C})$ and pressure $(P\approx \pu{1 \pm 0.5 bar})$

What should this chamber be called? I need the the name to be able to search for it and also mention in my publication. 


Candidate names so far:


* Incubator --> mostly for biological entities
* Reactor
* Environmental chamber --> too expensive
* Atmospheric controlled chamber
* Autoclave --> for sterilization(high temperature/pressure)
* Flash drum
* Vapor inhalation chambers --> for animal testing


P.S. I have posted the question also on Reddit [here](https://www.reddit.com/r/ChemicalEngineering/comments/7ij3m3/a_chamber_to_control_concentration_of_a_vapor_is/?st=jb01somf&sh=a9c0ae8a) and [here](https://www.reddit.com/r/chemistry/comments/7iix6a/a_chamber_to_control_concentration_of_a_vapor_is/?st=jb01sqjh&sh=7b8cbc85). There are some good points mentioned there.




There is a book [The Design of Controlled-atmosphere Chambers for the Study of Oxygen Toxicity](https://books.google.com/books?id=fbhjAAAAMAAJ&q=controlled%20atmosphere%20chamber&dq=controlled%20atmosphere%20chamber&hl=en&sa=X&ved=0ahUKEwjRhbbgnPvXAhWEQt8KHUAKCt8Q6AEIJzAA), so I suggest "contolled-atmosphere chamber".
