Zirconia

Explanation

The measuring principle of our oxygen sensor is based on the diffusion of oxygen from the sample gas through a ZrO2 (zirconia) cell to the ambient environment. Within the cell, there are inner and outer electrodes that measure the potential gradient. As oxygen molecules diffuse across the cell, a potential gradient is established, and this gradient is directly related to the concentration of oxygen in the sample gas. By measuring the change in potential gradient, we can determine the corresponding change in oxygen concentration. To establish a reference point, the ambient air is used as the baseline value against which the oxygen concentration in the sample gas is compared. This ensures accurate and reliable measurements by providing a consistent and reliable reference value. Our oxygen sensor utilizes this diffusion-based principle to provide precise and real-time measurements of oxygen concentration in various applications.
