Oxymitter 4000 In Situ Oxygen Analyzer
SKU: OXY4000
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.

6888 In Situ Oxygen Analyzer
Next-generation in-situ oxygen analyzer — successor to the Oxymitter 4000 with the 6888 Xi Transmitter providing centralized infrastructure for remote auto-calibration, diagnostic tools, alarm relays, and advanced application features. Two main probe variants: 6888A (general purpose) and 6888C (hazardous areas). Helps optimize industrial / commercial boilers, fired heaters, and kilns by analyzing oxygen in flue gas. The Plantweb-compatible modern choice for new builds; 4000 remains for installed-base retrofits.
OCX 8800 Oxygen and Combustibles Analyzer
Combustion-flue-gas analyzer that provides continuous, accurate measurement of oxygen AND combustibles in one transmitter — replaces two separate sensors with a single in-situ probe. Field-replaceable zirconium oxide O2 sensor and combustibles sensor. Operates in flue temperatures up to 2600°F (1427°C). Air-purge cycle improves cell calibration and effectiveness. Optional factory-built auto-calibration panel. HART, FOUNDATION Fieldbus, AMS/PlantWeb compatible. Best for boiler / furnace efficiency optimization (fuel-air ratio tuning) and emissions compliance — minimizes NOx, hazardous air pollutants, and other GHG emissions while saving fuel.
