Polcon - Pipe Caliper

The Polcon Pipe Caliper is used to accurately determine the inside pipe diameter, which is critical to determining the flow-rate through a pipe.  The inside diameter is always measured to the nearest 1/16 - inch, for accuracy. The unique design permits the accurate determination of the pipe diameter even if the tap extends through the pipe wall.  Constructed with high-grade brass and steel, Polcon® Pipe Calipers are both durable and accurate.  The “O” ring packing, and locking device provide a safe and leak-proof installation.
