  • Page 4: Preface

    Preface CO2-O2-UNIT-BL [0-20; 1-95] is a Digital CO2/O2 Controller that mixes CO2, O2 and N2 to the desired concentration in the CO2 range 0-20% and O2 range 1-95%. If operated without N2, it mixes CO2 and Air to the desired CO2 concentration in the range 0-20% and you don’t need to regulate O2.
