Corrosion Monitors
AGF’s CORRi n SITE™ Corrosion Monitors were developed in response to
the increase of corrosion-related failures in both wet and dry fire protection
systems. CORRin SITE™, available in an in-line pipe or mechanical tee,
provides a simple to install, maintenance-free, and inexpensive method to
monitor for hidden corrosion problems in any fire protection system.
The CORRin SITE™ is manufactured from the same mild carbon steel as the
system’s piping and its surface corrodes as the pipe corrodes. When the
monitor corrodes beyond it’s limit, moisture penetrates the sealed chamber
and transforms the brilliant white sight glass to a fluorescent orange color,
indicating a corrosion problem and need for further investigation.
