• Reaches operating temperature in under 7 seconds for quick closed-loop control
• Metal housing, integrated heater element and TSP coating resist vibration, corrosion and contamination
• Withstands exhaust streams up to 1,880°F
• Ceramic construction for steady readings through rapid load changes and harsh thermal cycles
