A Special Note About Corrosion

  • Excessive corrosion may result in leakage, glass breakage, and premature valve failure.
  • Be sure all wetted components of the gauge are constructed with materials compatible with the service medium. John C. Ernst Co. does not make chemical compatibility recommendations.
  • See the "Compass Corrosion Guide" or equivalent for material compatibility
