The Polatrak RT-1Z facilitates simple, on-line internal cathodic protection monitoring for vessels. The instrument may be left in place if on-line monitoring is required (a condulet adapter is available for this type of application). The instrument is rated to 150 PSI, and is therefore suitable for most produced water vessels. Access is through a 0.75" or larger full opening ball valve.
