As far as I know, this is not yet available.

Mmmmm, I'm not familiar with this, but would the Eheim CO2 quick test device
not do the same thing? As I believe George Booth (at least I think it was
George) explained to me last year, when I asked how the similar device from
Dupla works, the colour change you see in these devices is really the effect
on an indicator solution of the pH of the water vapour which moves through
it.
