The 4OXeco LP sensor from City Technology Ltd., Portsmouth, U.K., and Des Plaines, IL, is a lead-free catalytic oxygen sensor designed to measure oxygen content when used in flue gas analyzers in power stations and in industrial, commercial, and residential buildings. The device is optimized to improve accuracy, operational life, and resistance to cross-contamination in flue gas analyzers. It features a 5 yr. operating life, a T97 response time and RT97 recovery time that are typically <8 s, power consumption <0.21 mW, and the ability to operate in high carbon dioxide concentrations. The sensor is rated for use in 20%–90% continuous RH with up to 99% RH intermittent and is suitable for use in EN 50379-2 regulatory and EN 50379-3 nonregulatory analyzers.
