  • Page 5: Preface

    Preface CO2-O2-UNIT-BL [0-10; 0-1] is a Digital CO2/O2 Controller that mixes CO2, N2 and Air to the desired concentration in the CO2 range 0-10% and O2 range 0-1%. It features a long life Non Dispersive Infrared (NDIR) dual wave length CO2 detector and a O2 electrochemical sensor to ensure a high accuracy on the gas composition and a flow rate sensor to regulate output flow rate.
