As an ex-manufacturer of both static and dynamic instruments, I favour 
the so-called static ones with computer extrapolation as being more 
accurate. The so-called dynamic ones may give misleading results because 
of excess CO2 absorption and substrate leaching and they take longer to 
do the test. Note that the terminology is bad: as a rule, the static 
ones generally have a more rapid solution movement.

You have (had?) a static one next to a "semi-aqueous" cleaner in a plant 
in Ankara, making cellphones and military communications equipment, that 
I visited many years ago.
