Oxymitter 4000 In Situ Oxygen Analyzer

World's first in-situ zirconium-oxide-based oxygen transmitter for flue-gas measurement with an explosion-proof rating — combines an oxygen probe with field electronics in one compact package. Probe inserts directly into the flue-gas duct; no external sampling system needed. 4-20 mA O2 signal without external signal-conditioning. HART or FOUNDATION Fieldbus. Used by boiler operators to fine-tune burner fuel/air ratios for maximum efficiency. Best for boilers, kilns, process heaters, and reheat furnaces. The cost-effective alternative to the OCX 8800 when only O2 measurement (not combustibles) is needed.
