From the flue gas channel, a pump integrated into the device suctions flue gas and Leads it to an O2 sensor in the device. The gas leaves the sensor and passes through a small Opening in the floor of the VARIOx-2 housing.
The long sensor life makes the VARIOx-2 particularly cost-effective.
Measurements can be issued on site via an IR printer. The VARIOx-2 further features a PC interface for online data upload.
The Dräger VARIOx-2 is available in the model VARIOx-2 CO₂.
