How to Choose: Zirconia vs. Fuel Cell Oxygen Sensor

Zirconia Sensor

• Pros: Solid-state, low maintenance, unaffected by air exposure, cost-effective.
• Cons: Affected by organic solvents, may show high readings or suffer long-term damage.
• Best for: Low-solvent environments, minimal maintenance needs.

Fuel Cell Sensor

• Pros: Accurate readings, unaffected by solvents.
• Cons: Sensitive to air (fails in 7 days), requires replacement every 1-2 years, higher maintenance cost.
• Best for: High-solvent environments, precise measurements.

Recommendation:

• With solvents: Choose fuel cell for accuracy.
• Without solvents: Choose zirconia for durability and lower costs.
