• Monitors exhaust gases and helps reduce pollutants
• Electrodes made of a gas-permeable platinum layer
• Determines the oxygen content of the exhaust gas to monitor the air-fuel ratio
• Coating protects the electrode surfaces from contamination and erosion by combustion residue and particulates
• Narrow-band sensing with a 4-wire connection
