        871DO-C Dissolved Oxygen Sensor

        871DO Sensor 873DO / EC / RS Analyzer The 871DO is a rugged dissolved oxygen sensor used for parts-per-million level measurements in industrial and municipal installations. The 871DO sensor is housed in a thermoplastic body. It is a rebuildable style sensor with a tough stainless steel reinforced composite membrane bonded to an easily replaceable membrane cap. Membrane caps and replacement electrolyte are the only spare parts, and with regular maintenance, the probe can last several years, even in the most difficult applications. Installation of the 871DO is accomplished through the use of built-in 1 inch NPT threads on the sensor body and the selection of an appropriate mounting adaptor. In applications where sulfur containing gases are dissolved in the liquid stream, the 871DO resists poisoning of the reference electrode through the use of an isolated reference design. When used with the 873DO analyzer, the 871DO offers several diagnostic routines, including membrane fouling, membrane breakage, and loss of internal filling solution.

        Benefits

      • 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
      • 24/7 expert technical and application support


      • Applications

      • Aeration basins
      • Industrial waste water treatment plants
      • Municipal waste water treatment plants
      • Aquaculture measurements
