Oxygen Measurement Retractable Assemblies

Sterilisable retractable Assembly for pH/Redox Measurement in Tanks or Pipelines Applications The retractable pH assembly CleanFit H CPA 475 is used wherever very exacting sanitary and hygienic demands are placed on the measuring equipment; the pH electrode is to be sterilised, calibrated or cleaned without interrupting the process; the pH electrodes are not to be removed between batches but must be kept wet; high-accuracy, low-maintenance, sterilisable pH electrodes are required Features and Benefits High-quality products are produced in the foodstuffs industry and in the fermentation processes of the pharmaceutical and biotech industries. Product yield and quality are affected by minimal deviations of the pH value. A pH control system optimally adapted to the measuring task at hand helps save on costs. With 3A certificate (EHEDG certification pending) For 120 mm / 4.72" gel electrodes or 225 mm / 8.86" liquid KCI electrodes as well as oxygen sensor COS 21 All parts in contact with the medium are made of stainless steel 1.4404 (AISI 316L), the seals consist of EPMD or VITON according to FDA recommendations.
