CO2 Controllers
The CO2-200 carbon dioxide controller has an internal CO2 sensor. It
controls the concentration of CO2 in a background gas from 0.5–15%.
This controller offers:
● A background flow rate of 25–250mL/min
● Optional air pump (not included) for economical use (as opposed to
using bottle pressurized background gas)
● In the future, multiple gas controllers of this variety can be daisy
chained
