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
