The FCX-ULL is a ceramic amperometric oxygen sensor using a zirconia solid-electrolyte with a limiting current method, designed for measuring oxygen concentrations from 0 to 1000 ppm. It operates with a sensing voltage of 0.7 V and a heater power of 2 W DC, producing an output current between 35 and 75 μA at 1000 ppm O₂. The sensor has an accuracy within 50 ppm, a response time of 30 seconds to 90% value, and a warm-up time of approximately 3 minutes. It functions in an operating temperature range of -10 to 50 °C and a storage range of -40 to 120 °C, with humidity tolerance up to 85% RH without condensation. The unit weighs approximately 5.5 g and complies with RoHS standards. The sensor has a rated lifetime of one year under continuous use in free air.
