Rosemount Analytical in situ Model 5081FG mounts close to process heater, furnace, or incinerator for readings accurate to ±1.5%. HART protocol delivers reliable measurements and device status, as well as remote diagnostics and calibration. Analyzer uses zirconium oxide sensor cell constructed of ceramic materials to measure excess oxygen in temperatures ranging from 550-1,400°C. Intrinsically safe design eliminates need for cell heater.
