Barben Analytical offers optical oxygen analyzers utilizing quench luminescence technology. The analyzers measure 25% O2 down to trace, 0.5 ppm O2, suitable for use in Haz. Loc. areas (FM:CID2, TUV:ATEX Zone2) and process streams including hydrocarbons, H2, H2S, Salts, Amines and CO2 without degradation.  The sensors are membrane free and able to work in dirty, high particulate and high moisture streams.

The analyzer is suitable for direct field installation (NEMA 4X) in hazardous area (Class I, Division 2). The optical fiber sensor platform allows small inline sensors to be installed into sample tubing lines (1/4”), flow cells using NPT fittings, or directly into tanks or process lines using our retractable “hot tap” sensor design. BOS optical oxygen sensors are impervious to typical O2 poisons (H2S) and interferences (combustibles, magnetic, CO2 and H2) with high accuracy and long-term stability measurements without the need for complex or advanced sample conditioning systems. The threaded version of the optical sensor has optional Dual Seal (ANSI/ISA 12.27.01) classification for high pressure applications up to 1200 PSIG (82.7 BAR).
