Part of Honeywell's Automotive & Emissions range. City Technology offers a comprehensive range of automotive and emissions sensors, including the AO2, AO3, 2FO, and NX1 models. These sensors are designed to provide accurate and reliable measurements essential for vehicle safety, performance, and environmental compliance.AO2 Oxygen Sensor - The AO2 is a CiTiceL® oxygen (O₂) gas sensor designed for automotive applications. It measures oxygen concentrations up to 100% volume, making it suitable for monitoring exhaust gases and ensuring optimal combustion efficiency. Manufactured in the UK, the AO2 sensor is known for its precision and durability. AO3 Oxygen Sensor - Similar to the AO2, the AO3 is a CiTiceL® oxygen (O₂) gas sensor that measures oxygen levels up to 100% volume. It is designed for use in automotive emissions systems to monitor and control air-fuel ratios, contributing to reduced emissions and improved fuel economy. 2FO Oxygen Sensor - The 2FO is an oxygen (O₂) gas sensor measuring up to 25% volume. It is commonly used in automotive applications to monitor ambient oxygen levels, ensuring passenger safety and optimal engine performance. NX1 NOx Sensor - The NX1 is a nitrogen oxide (NOx) sensor designed to detect and measure NOx concentrations in vehicle exhaust systems. Accurate NOx measurement is crucial for compliance with environmental regulations and for the efficient operation of selective catalytic reduction (SCR) systems used to reduce NOx emissions.City Technology's sensors are integral components in modern automotive systems, contributing to vehicle efficiency, safety, and environmental responsibility.
