Dräger MSI VARIOx-2 is a complete family of electronic single gas analysers for the
determination of gas concentrations from flue gases of combustion and industrial
processes.

It is available in seven versions to measureO2, CO2, CO, NO, NO2 or SO2. All versionsare equipped with an internal pump thatdraws a gas sample via a gas conditioningcartridge through an extraction probeand leads it into a sensor chamber toan electrochemical sensor. The gasconcentration is displayed in real-time andcan be printed or transmitted to a PC.
