The CORRinSITE is a corrosion monitor for wet, dry, or preaction sprinkler systems and manufactured from the same mild carbon steel as the system's piping. The "plug's" surface sits at the same depth as the pipe wall and therefore, corrodes at the same rate as the pipe. When the monitor's plug corrodes beyond its limit, moisture penetrates the sealed chamber and transforms the brilliant white sight glass to a fluorescent orange color indicating a corrosion problem and a need for further pipe inspection.
The CORRinSITE was developed in response to the increase of corrosion related failures in both wet and dry fire protection systems. CORRinSITE, available in an in-line pipe and mechanical tee, provides a simple to install, maintenance-free, and inexpensive method to monitor for hidden corrosion problems in any fire protection system.

2 - Treat all water that enters the system using an approved corrosion inhibitor
3 - Implement an approved plan for monitoring the interior conditions of the pipe at established intervals and locations
4 - Install corrosion monitoring station and monitor at established intervals
