The design of the reference gas channel must ensure it is not easily blocked in harsh environments, such as avoiding dust, moisture, or chemicals from entering. Users should regularly inspect and clean the channel to maintain its functional integrity. If the reference gas port becomes blocked, the inner electrode will not receive a stable oxygen partial pressure reference value, leading to measurement deviations or drifts, and in severe cases, may trigger false alarms or damage the equipment. Therefore, during installation and maintenance, always choose a clean operating location and use appropriate tools such as soft brushes or low-pressure air streams for cleaning.
