        871DO Sensor
        873DO / EC / RS Analyzer
        Foxboro Dissolved Oxygen Products

        The Foxboro dissolved oxygen range consists of an 871DO sensor and 873DO analyzer. The 871DO is a rugged dissolved oxygen sensor used for parts-per-million level measurements in industrial and municipal installations. It is a rebuildable style sensor with a tough stainless steel reinforced composite membrane bonded to an easily replaceable membrane cap. When used with the 873DO analyzer, the 871DO offers several diagnostic routines, including membrane fouling, membrane breakage, and loss of internal filling solution. The Foxboro 873DO is a line-powered, dual sensor input dissolved oxygen analyzer. Calibration of the 873DO is quick and simple, achieved by allowing the sensor to stabilize in ambient air. Each 873DO analyzer provides two analog output signals (4-20 mA, 0-10 V, 0-20 mA) and two alarm relays.
      • Rugged sensor with reinforced composite membrane delivers long, reliable life
      • Easily replaceable membrane cap assembly save time for routine maintenance
      • Advanced diagnostics warn if the sensor needs to be serviced
      • Fast and easy air calibration reduces maintenance time and cost
      • Analyzer can accept either one or two sensor signals
      • 24/7 expert technical and application support
      • Aeration basins
      • Industrial waste water treatment plants
      • Municipal waste water treatment plants
      • Aquaculture measurements
