A Special Note About Corrosion
• Excessive corrosion may result in leakage, glass
   breakage, and premature valve failure.
• Be sure all wetted components of the g auge 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
